AZL-66539 CVE-2025-38565 affecting package kernel for versions less than 6.6.104.2-1

In the Linux kernel, the following vulnerability has been resolved: perf/core: Exit early on perfmmap fail When perfmmap fails to allocate a buffer, it still invokes the eventmapped callback of the related event. On X86 this might increase the perfrdpmcallowed reference counter. But nothing undoe...

CVE-2025-38565

CVE-2025-38565: In the Linux kernel perf_mmap() path, if buffer allocation fails the code still invokes event_mapped(), which can increment perf_rdpmc_allowed on x86 and leaks references because perf_mmap_close() is not called. The documented fix is to return early on failure to prevent the refer...

CVE-2025-38563

CVE-2025-38563 affects the Linux kernel perf subsystem. The issue arises when perf mmap-based mappings can be split (VMA split) after initial mapping, causing mismatched offsets/sizes and leaking reference counts for ringbuffer/auxiliary buffers. The fix adds vm_operations_struct.may_split() and ...
