CVE-2024-35983

A vulnerability was found in the Linux kernel related to the improper handling of power-of-two values for CONFIGNRCPUS. The bitsper function incorrectly rounds up to the next power of two when given a power of two, causing crashes on certain systems. Mitigation Mitigation for this issue is either...

CVE-2021-46910

In the Linux kernel, the following vulnerability has been resolved: ARM: 9063/1: mm: reduce maximum number of CPUs if DEBUGKMAPLOCAL is enabled The debugging code for kmaplocal doubles the number of per-CPU fixmap slots allocated for kmaplocal, in order to use half of them as guard regions. This...

CVE-2021-46910

CVE-2021-46910 relates to the Linux kernel’s kmap_local(): when CONFIG_DEBUG_KMAP_LOCAL=y, per-CPU fixmap slots are doubled, causing the fixmap region to grow downwards and potentially collide with the virtual DT mapping. The documented impact is a local exploit path leading to kernel instability...
