GCVE-110-MAGEIA-2022-122

This kernel-linus update is based on upstream 5.15.32 and fixes at least the following security issues: An out-of-bounds (OOB) memory write flaw was found in the Linux kernel’s watch_queue event notification subsystem. This flaw can overwrite parts of the kernel state, potentially allowing a local user to gain privileged access or cause a denial of service on the system (CVE-2022-0995). A flaw use after free in the Linux kernel FUSE filesystem was found in the way user triggers write(). A local user could use this flaw to get some unauthorized access to some data from the FUSE filesystem and as result potentially privilege escalation too (CVE-2022-1011). A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem. This flaw allows a local user to cause an out-of-bounds write issue (CVE-2022-1015). A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c: nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker (CVE-2022-1016). A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system (CVE-2022-1048). st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c has EVT_TRANSACTION buffer overflows because of untrusted length parameters (CVE-2022-26490). There is a buffer overflow in ESP transformation in net/ipv4/esp4.c and net/ipv6/esp6.c via a large message. In some configurations, local users can gain privileges by overwriting kernel heap objects (CVE-2022-27666). A refcount leak bug was found in net/llc/af_llc.c (CVE-2022-28356). For other upstream fixes, see the referenced changelogs.
