Description

Updated kernel packages fix security vulnerabilities This kernel update is based on upstream 5.10.75 and fixes at least the following security issues: A memory leak in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ ccp/ccp-ops.c in the Linux kernel allows malicious users to cause a denial of service (memory consumption) (CVE-2021-3744). A memory leak flaw was found in the Linux kernel's ccp_run_aes_gcm_cmd() function that allows an malicious user to cause a denial of service (CVE-2021-3764). A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users do rename in specific way with OverlayFS. A local user could use this flaw to crash the system (CVE-2021-20321). prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel through 5.14.9 allows unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write (CVE-2021-41864). For other upstream fixes, see the referenced changelogs.

A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95% (CVE-2023-1206). A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system (CVE-2023-4004). A use-after-free flaw was found in the Linux kernel’s Netfilter functionality when adding a rule with NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system (CVE-2023-4147). A side channel vulnerability in some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled instruction pointer register, potentially leading to information disclosure (CVE-2023-20569). A buffer overrun vulnerability was found in the netback driver in Xen due to an unusual split packet. This flaw allows an unprivileged guest to cause a denial of service (DoS) of the host by sending network packets to the backend, causing the backend to crash (CVE-2023-34319, XSA-432). Security fix for AMD Zen1 information leak through Divide By Zero.

A remote user could use this flaw to crash the system. This is fixed by removing DECnet support (CVE-2023-3338). A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue (CVE-2023-3390). Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; nft_chain_lookup_byid() failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace (CVE-2023-31248). Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace (CVE-2023-35001). NOTE!! This kernel also contains a fix for dkms builds hanging / stalling during upgrade to Mageia 9 (mga#31982) due to the new make 4.4 series utility ending up in a loop processing Makefile in kernel-devel packages. So if you use dkms packaged drivers, you need to be running this kernel (or any later released ones) before you do an online upgrade to avoid the upgrade stalling / hanging.

An out-of-bounds memory access flaw was found in the Linux kernel’s XFS file system in how a user restores an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or potentially escalate their privileges on the system (CVE-2023-2124). A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol. This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the system (CVE-2023-2156). A denial of service problem was found, due to a possible recursive locking scenario, resulting in a deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-component (CVE-2023-2269). A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading to a kernel information leak (CVE-2023-3141). A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic (CVE-2023-3212). An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel internal information (CVE-2023-3268). An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event, down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and down(&fepriv->sem) may block the process (CVE-2023-31084). In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled (CVE-2023-32233). An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an offset (CVE-2023-34256). An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7. It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets. This may result in denial of service or privilege escalation (CVE-2023-35788). An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in saa7134_finidev in drivers/media/pci/saa7134/saa7134-core.c (CVE-2023-35823). An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in dm1105_remove in drivers/media/pci/dm1105/dm1105.c (CVE-2023-35824). An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in renesas_usb3_remove in drivers/usb/gadget/udc/renesas_usb3.c (CVE-2023-35828). An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in rkvdec_remove in drivers/staging/media/rkvdec/rkvdec.c (CVE-2023-35829).

This issue could occur when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading to a denial of service (CVE-2023-1380). It was discovered that a race condition existed in the Xen transport layer implementation for the 9P file system protocol in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or expose sensitive information (CVE-2023-1859). An insufficient permission check has been found in the Bluetooth subsystem of the Linux kernel when handling ioctl system calls of HCI sockets. This causes tasks without the proper CAP_NET_ADMIN capability can easily mark HCI sockets as _trusted_. Trusted sockets are intended to enable the sending and receiving of management commands and events, such as pairing or connecting with a new device. As a result, unprivileged users can acquire a trusted socket, leading to unauthorized execution of management commands (CVE-2023-2002). A heap out-of-bounds read/write vulnerability in the Linux Kernel traffic control (QoS) subsystem can be exploited to achieve local privilege escalation. The qfq_change_class function does not properly limit the lmax variable which can lead to out-of-bounds read/write. If the TCA_QFQ_LMAX value is not offered through nlattr, lmax is determined by the MTU value of the network device. The MTU of the loopback device can be set up to 2^31-1 and as a result, it is possible to have an lmax value that exceeds QFQ_MIN_LMAX (CVE-2023-2248). qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write because lmax can exceed QFQ_MIN_LMAX (CVE-2023-31436). Linux kernel use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary reads and writes in kernel memory. An unprivilegied local user can exploit this to start a local root shell (CVE-2023-32233).

The tun/tap sockets have their socket UID hardcoded to 0 due to a type confusion in their initialization function. While it will be often correct, as tuntap devices require CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing network filters (CVE-2023-1076). In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption (CVE-2023-1077). A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data (CVE-2023-1079). A flaw use after free in the Linux kernel integrated infrared receiver/ transceiver driver was found in the way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate their privileges on the system (CVE-2023-1118). A use-after-free flaw was found in btrfs_search_slot in fs/btrfs/ctree.c in btrfs in the Linux Kernel.This flaw allows an attacker to crash the system and possibly cause a kernel information leak (CVE-2023-1611). A flaw use after free in the Linux kernel Xircom 16-bit PCMCIA (PC-card) Ethernet driver was found.A local user could use this flaw to crash the system or potentially escalate their privileges on the system (CVE-2023-1670). A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root (CVE-2023-1829). A use-after-free flaw was found in xgene_hwmon_remove in drivers/hwmon/ xgene-hwmon.c in the Hardware Monitoring Linux Kernel Driver (xgene-hwmon). This flaw could allow a local attacker to crash the system due to a race problem. This vulnerability could even lead to a kernel information leak problem (CVE-2023-1855). A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\ btsdio.c in the Linux Kernel. In this flaw, a call to btsdio_remove with an unfinished job, may cause a race problem leading to a UAF on hdev devices (CVE-2023-1989). A use-after-free flaw was found in ndlc_remove in drivers/nfc/st-nci/ndlc.c in the Linux Kernel. This flaw could allow an attacker to crash the system due to a race problem (CVE-2023-1990). A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition (CVE-2022-4269). A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel. This flaw allows an attacker to conduct a remote denial of service (CVE-2022-4379). The Linux kernel through 6.1.9 has a Use-After-Free in bigben_remove in drivers/hid/hid-bigbenff.c via a crafted USB device because the LED controllers remain registered for too long (CVE-2023-25012). do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference) (CVE-2023-28466). An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64 lacks consistency checks for CR0 and CR4 (CVE-2023-30456). The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in drivers/power/supply/da9150-charger.c if a physically proximate attacker unplugs a device (CVE-2023-30772).
