Summary
Important: kernel-rt security and bug fix update
Details

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

  • kernel: use-after-free in l2cap_connect and l2cap_le_connect_req in net/bluetooth/l2cap_core.c (CVE-2022-42896)
  • kernel: tcindex: use-after-free vulnerability in traffic control index filter allows privilege escalation (CVE-2023-1281)
  • kernel: Use-after-free vulnerability in the Linux Kernel traffic control index filter (CVE-2023-1829)
  • kernel: use-after-free vulnerability in the perf_group_detach function of the Linux Kernel Performance Events (CVE-2023-2235)
  • kernel: OOB access in the Linux kernel's XFS subsystem (CVE-2023-2124)
  • kernel: i2c: out-of-bounds write in xgene_slimpro_i2c_xfer() (CVE-2023-2194)
