kernel: speculative pointer dereference in do_prlimit() in kernel/sys.c

A vulnerabilty was found in Linux Kernel, where a speculative pointer dereference problem exists in the Linux Kernel on the doprlimit function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents...

USN-6341-1 linux vulnerabilities

Jordy Zomer and Alexandra Sandulescu discovered that syscalls invoking the doprlimit function in the Linux kernel did not properly handle speculative execution barriers. A local attacker could use this to expose sensitive information kernel memory. CVE-2023-0458 It was discovered that a...

USN-6093-1 linux-bluefield vulnerabilities

It was discovered that the Traffic-Control Index TCINDEX implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the...

CVE-2023-0458 Spectre V1 Gadget in do_prlimit in the Linux Kernel

A speculative pointer dereference problem exists in the Linux Kernel on the doprlimit function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents. We recommend upgrading past version 6.1.8 or...
