Vulnerability from osv_almalinux – Published: 2021-06-01 09:02 – Updated: 2021-08-11 08:54 – Source websiteThe kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
-
kernel: userspace applications can misuse the KVM API to cause a write of 16 bytes at an offset up to 32 GB from vcpu->run (CVE-2021-3501)
-
kernel: nitro_enclaves stale file descriptors on failed usercopy (CVE-2021-3543)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
-
OVS mistakenly using local IP as tun_dst for VXLAN packets (?) (BZ#1944667)
-
Selinux: The task calling security_set_bools() deadlocks with itself when it later calls selinux_audit_rule_match(). (BZ#1945123)
-
[mlx5] tc flower mpls match options does not work (BZ#1952061)
-
mlx5: missing patches for ct.rel (BZ#1952062)
-
CT HWOL: with OVN/OVS, intermittently, load balancer hairpin TCP packets get dropped for seconds in a row (BZ#1952065)
-
[Lenovo 8.3 bug] Blackscreen after clicking on "Settings" icon from top-right corner. (BZ#1952900)
-

-
P620 no sound from front headset jack (BZ#1954545)
-
AlmaLinux kernel 8.2 and higher are affected by data corruption bug in raid1 arrays using bitmaps. (BZ#1955188)
