USN-6090-1: Linux kernel vulnerabilities<\/p>\n
It was discovered that some AMD x86-64 processors with SMT enabled could
\nspeculatively execute instructions using a return address from a sibling
\nthread. A local attacker could possibly use this to expose sensitive
\ninformation. (CVE-2022-27672)<\/p>\n
Zheng Wang discovered that the Intel i915 graphics driver in the Linux
\nkernel did not properly handle certain error conditions, leading to a
\ndouble-free. A local attacker could possibly use this to cause a denial of
\nservice (system crash). (CVE-2022-3707)<\/p>\n
Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did
\nnot properly implement speculative execution barriers in usercopy functions
\nin certain situations. A local attacker could use this to expose sensitive
\ninformation (kernel memory). (CVE-2023-0459)<\/p>\n
It was discovered that the TLS subsystem in the Linux kernel contained a
\ntype confusion vulnerability in some situations. A local attacker could use
\nthis to cause a denial of service (system crash) or possibly expose
\nsensitive information. (CVE-2023-1075)<\/p>\n
It was discovered that the Reliable Datagram Sockets (RDS) protocol
\nimplementation in the Linux kernel contained a type confusion vulnerability
\nin some situations. An attacker could use this to cause a denial of service
\n(system crash). (CVE-2023-1078)<\/p>\n
Xingyuan Mo discovered that the x86 KVM implementation in the Linux kernel
\ndid not properly initialize some data structures. A local attacker could
\nuse this to expose sensitive information (kernel memory). (CVE-2023-1513)<\/p>\n
It was discovered that the Android Binder IPC subsystem in the Linux kernel
\ndid not properly validate inputs in some situations, leading to a use-
\nafter-free vulnerability. A local attacker could use this to cause a denial
\nof service (system crash) or possibly execute arbitrary code.
\n(CVE-2023-20938)<\/p>\n
It was discovered that a use-after-free vulnerability existed in the iSCSI
\nTCP implementation in the Linux kernel. A local attacker could possibly use
\nthis to cause a denial of service (system crash). (CVE-2023-2162)<\/p>\n
It was discovered that the NET\/ROM protocol implementation in the Linux
\nkernel contained a race condition in some situations, leading to a use-
\nafter-free vulnerability. A local attacker could use this to cause a denial
\nof service (system crash) or possibly execute arbitrary code.
