USN-6124-1: Linux kernel (OEM) vulnerabilities<\/p>\n
Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in
\nthe netfilter subsystem of the Linux kernel when processing batch requests,
\nleading to a use-after-free vulnerability. A local attacker could use this
\nto cause a denial of service (system crash) or possibly execute arbitrary
\ncode. (CVE-2023-32233)<\/p>\n
Reima Ishii discovered that the nested KVM implementation for Intel x86
\nprocessors in the Linux kernel did not properly validate control registers
\nin certain situations. An attacker in a guest VM could use this to cause a
\ndenial of service (guest crash). (CVE-2023-30456)<\/p>\n
Gwnaun Jung discovered that the SFB packet scheduling implementation in the
\nLinux kernel contained a use-after-free vulnerability. A local attacker
\ncould use this to cause a denial of service (system crash) or possibly
\nexecute arbitrary code. (CVE-2022-3586)<\/p>\n
It was discovered that the Intel i915 graphics driver in the Linux kernel
\ndid not perform a GPU TLB flush in some situations. A local attacker could
\nuse this to cause a denial of service or possibly execute arbitrary code.
\n(CVE-2022-4139)<\/p>\n
It was discovered that the Xircom PCMCIA network device driver in the Linux
\nkernel did not properly handle device removal events. A physically
\nproximate attacker could use this to cause a denial of service (system
\ncrash). (CVE-2023-1670)<\/p>\n

\nLinux kernel contained a race condition when handling inode locking in some
\nsituations. A local attacker could use this to cause a denial of service
\n(kernel deadlock). (CVE-2023-2612)
