CVE-2023-0458: Debian Linux

Medium severity, CVSS 4.7. EPSS: 0.7% chance of exploitation in the next 30 days.

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. We recommend upgrading past version 6.1.8 or commit 739790605705ddcf18f21782b9c99ad7d53a8c11

Affected products

• Debian Debian Linux: version 10.0 only
• Linux Linux Kernel: before 6.1.8 (fixed in 6.1.8); version 6.2 only
