It was discovered that a race condition existed in the overlay file system
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash). (CVE-2021-20321)
It was discovered that the virtual terminal (vt) device implementation in
the Linux kernel contained a race condition in its ioctl handling that led
to an out-of-bounds read vulnerability. A local attacker could possibly use
this to expose sensitive information. (CVE-2021-3753)
It was discovered that the ext4 file system implementation in the Linux
kernel contained a use-after-free vulnerability. An attacker could use this
to construct a malicious ext4 file system image that, when mounted, could
cause a denial of service (system crash). (CVE-2022-1184)
Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan
and Ariel Sabba discovered that some Intel processors with Enhanced
Indirect Branch Restricted Speculation (eIBRS) did not properly handle RET
instructions after a VM exits. A local attacker could potentially use this
to expose sensitive information. (CVE-2022-26373)
Johannes Wikner and Kaveh Razavi discovered that for some Intel x86-64
processors, the Linux kernel’s protections against speculative branch
target injection attacks were insufficient in some circumstances. A local
attacker could possibly use this to expose sensitive information.
(CVE-2022-29901)
It was discovered that the ST NCI NFC driver did not properly handle device
removal events. A physically proximate attacker could use this to cause a
denial of service (system crash). (CVE-2023-1990)
It was discovered that the btrfs file system implementation in the Linux
kernel did not properly handle error conditions in some situations, leading
to a use-after-free vulnerability. A local attacker could possibly use this
to cause a denial of service (system crash). (CVE-2023-3111)
