Linux · Linux Kernel · CVE-2023-0458
**Name of the Vulnerable Software and Affected Versions**
Linux Kernel versions prior to 6.1.8
**Description**
A speculative pointer dereference problem exists in the Linux Kernel on the `do prlimit()` 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.
**Recommendations**
Upgrade past version 6.1.8 or apply commit 739790605705ddcf18f21782b9c99ad7d53a8c11 to resolve the issue. As a temporary workaround, consider restricting access to the `do prlimit()` function until a patch is available.
