- Summary
- Updated kernel packages fix security vulnerabilities
- Details
-
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//maps for exploitation (CVE-2021-41073).
For other upstream fixes, see the referenced changelogs.
