USN-6312-1

It was discovered that the netlink implementation in the Linux kernel did not properly validate policies when parsing attributes in some situations. An attacker could use this to cause a denial of service (infinite recursion). (CVE-2020-36691)

Billy Jheng Bing Jhong discovered that the CIFS network file system implementation in the Linux kernel did not properly validate arguments to ioctl() in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-0168)

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)

It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. (CVE-2022-27672)

William Zhao discovered that the Traffic Control (TC) subsystem in the Linux kernel did not properly handle network packet retransmission in certain situations. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2022-4269)

It was discovered that a race condition existed in the qdisc implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-0590)

It was discovered that a race condition existed in the btrfs file system implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-1611)

It was discovered that the APM X-Gene SoC hardware monitoring driver in the Linux kernel contained a race condition, leading to a...
