The SUSE Linux Enterprise 15 SP3 Azure kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2021-3573: Fixed an UAF vulnerability in function that can allow attackers to corrupt kernel heaps and adopt further exploitations. (bsc#1186666) - CVE-2021-0605: Fixed an out-of-bounds read which could lead to local information disclosure in the kernel with System execution privileges needed. (bsc#1187601) - CVE-2021-0512: Fixed a possible out-of-bounds write which could lead to local escalation of privilege with no additional execution privileges needed. (bsc#1187595) - CVE-2021-33624: Fixed a bug which allows unprivileged BPF program to leak the contents of arbitrary kernel memory (and therefore, of all physical memory) via a side-channel. (bsc#1187554) - CVE-2021-34693: Fixed a bug in net/can/bcm.c which could allow local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized.
