The SUSE Linux Enterprise 12 SP4 kernel was updated.
The following security bugs were fixed:
- CVE-2022-0812: Fixed an incorrect header size calculations which could lead to a memory leak. (bsc#1196639)
- CVE-2021-39713: Fixed a race condition in the network scheduling subsystem which could lead to a use-after-free. (bnc#1196973)
- CVE-2022-27666: Fixed a buffer overflow vulnerability in IPsec ESP transformation code. This flaw allowed a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation. (bnc#1197462)
- CVE-2022-1016: Fixed a vulnerability in the nf_tables component of the netfilter subsystem. This vulnerability gives an attacker a powerful primitive that can be used to both read from and write to relative stack data, which can lead to arbitrary code execution. (bsc#1197227)
- CVE-2022-28389: Fixed a double free in drivers/net/can/usb/mcba_usb.c vulnerability in the Linux kernel. (bnc#1198033)
- CVE-2022-28356: Fixed a refcount bug in llc_ui_bind and llc_ui_autobind which could allow an unprivileged user to execute a DoS. (bnc#1197391)
- CVE-2022-28388: Fixed a double free in drivers/net/can/usb/usb_8dev.c vulnerability in the Linux kernel. (bnc#1198032)
- CVE-2022-28390: Fixed a double free in drivers/net/can/usb/ems_usb.c vulnerability in the Linux kernel. (bnc#1198031)
- CVE-2022-1048: Fixed a race Condition in snd_pcm_hw_free leading to use-after-free due to the AB/BA lock with buffer_mutex and mmap_lock. (bsc#1197331)
- CVE-2022-0850: Fixed a kernel information leak vulnerability in iov_iter.c. (bsc#1196761)
- CVE-2022-26966: Fixed an issue in drivers/net/usb/sr9700.c, which allowed attackers to obtain sensitive information from the memory via crafted frame lengths from a USB device. (bsc#1196836)
- CVE-2021-45868: Fixed a wrong validation check in fs/quota/quota_tree.c which could lead to an use-after-free if there is a corrupted quota file. (bnc#1197366)
