script_tag(name:"insight", value:"This kernel-linus update is based on upstream 5.15.41 and fixes at least the
following security issues:
A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading
to a possible out-of-bounds memory write in the Linux kernel BPF subsystem
due to the way a user loads BTF. This flaw allows a local user to crash or
escalate their privileges on the system. NOTE: Mageia kernels by default
prevents unprivileged users from being able to use eBPF so this would
require a privileged user with CAP_SYS_ADMIN or root to be able to abuse
this flaw reducing its attack space (CVE-2022-0500).
Due to the small table perturb size, a memory leak flaw was found in the
Linux kernel's TCP source port generation algorithm in the net/ipv4/tcp.c
function. This flaw allows an attacker to leak information and may cause
a denial of service (CVE-2022-1012).
A flaw was found in the Linux kernel's nfcmrvl_nci_unregister_dev()
function. A race condition leads to a use-after-free issue when simulating
the NFC device from the user space (CVE-2022-1734).
A flaw was found in the Linux kernel's adjust_ptr_min_max_vals in the
kernel/bpf/verifier.c function. In this flaw, a missing sanity check for
*_OR_NULL pointer types that perform pointer arithmetic may cause a kernel
information leak issue. NOTE: Mageia kernels by default prevents
unprivileged users from being able to use eBPF so this would require a
privileged user with CAP_SYS_ADMIN or root to be able to abuse this flaw
reducing its attack space (CVE-2022-23222).
The SUNRPC subsystem in the Linux kernel through 5.17.2 can call
xs_xprt_free before ensuring that sockets are in the intended state
(CVE-2022-28893).
Improper Update of Reference Count vulnerability in net/sched of Linux
Kernel allows local attacker to cause privilege escalation to root
(CVE-2022-29581).
For other upstream fixes, see the referenced changelogs.");
