Summary

linux-oem-6.0 vulnerabilities

Details

It was discovered that the Upper Level Protocol (ULP) subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, 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-2023-0461)

It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-43945)

Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42896)

It was discovered that the IPv6 implementation in the Linux kernel contained a data race condition. An attacker could possibly use this to cause undesired behaviors. (CVE-2022-3567)

It was discovered that the NFSD implementation in the Linux kernel contained a use-after-free vulnerability. A remote attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-4379)

It was discovered that an integer overflow vulnerability existed in the Bluetooth subsystem in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2022-45934)

It was discovered that the Atmel WILC1000 driver in the Linux kernel did not properly validate offsets, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service (system crash). (CVE-2022-47520)

José Oliveira and Rodrigo Branco discovered that the prctl syscall implementation in the Linux kernel did not properly protect against indirect branch prediction attacks in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2023-0045)

It was discovered that the io_uring subsystem in the Linux kernel contained a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-0469)
