The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * kernel: use-after-free in l2cap_connect and l2cap_le_connect_req in net/bluetooth/l2cap_core.c * kernel: tcindex: use-after-free vulnerability in traffic control index filter allows privilege escalation * kernel: Use-after-free vulnerability in the Linux Kernel traffic control index filter * kernel: use-after-free vulnerability in the perf_group_detach function of the Linux Kernel Performance Events * kernel: OOB access in the Linux kernel"s XFS subsystem * kernel: i2c: out-of-bounds write in xgene_slimpro_i2c_xfer For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
