Description

Updated kernel packages fix security vulnerabilities This kernel update is based on upstream 5.10.70 and fixes at least the following security issues: Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP socket with an attached dccps_hc_tx_ccid object as a listener after being released (CVE-2020-16119). oop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc/<pid>/maps for exploitation (CVE-2021-41073). For other upstream fixes, see the referenced changelogs.
