CVE-2026-97991

The Linux kernel contains a vulnerability in vdpa_sim_blk where the vdpasim_blk_check_range() function logs an invalid start sector but fails to halt validation. This allows an unsigned capacity subtraction to underflow, leading to an out-of-range buffer offset reaching the data path. The invalid...

CVE-2026-97943 x86/mm/pat: Acquire init_mm write lock on collapse to avoid UAF

In the Linux kernel, the following vulnerability has been resolved: x86/mm/pat: Acquire initmm write lock on collapse to avoid UAF x86 implements page attribute modification using its Change Page Attributes CPA mechanism. This tracks properties of ranges such as cache mode through x86 page...

CVE-2026-97943

The Linux kernel contains a vulnerability in the x86 architecture's Change Page Attributes (CPA) mechanism. Specifically, the cpa_collapse_large_pages() function can collapse kernel page table entries into huge page table entries and free the old page tables without holding necessary locks. This ...

CVE-2026-97936

The Linux kernel contains a memory corruption vulnerability in the tracing subsystem. The event_hist_trigger() function performs an unbounded memcpy when handling the histogram stacktrace modifier, using a count directly from the event data. This allows for an out-of-bounds write that can overwri...
