The vulnerability of the pte_fragDestroy() function in the arch/powerpc/mm/pgtable-frag.c module of the PowerPC platform in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the ptefragDestroy function in the arch/powerpc/mm/pgtable-frag.c module of the Linux operating system’s PowerPC platform is related to the state of the race condition when a shared resource is used. Exploiting this vulnerability could allow an attacker to compromise the...

CVE-2026-80626

A flaw was found in the Linux kernel's powerpc/perf component. An issue in the fslembpmudel function can lead to a preempt count underflow. This occurs when the function attempts to decrement a preemption counter without a corresponding increment, specifically when event-hw.idx is negative. On...
