CVE-2026-89582

This double free vulnerability affects the bnx2x network driver in the Linux kernel . In the error path of bnx2x_init_firmware(), the pointers bp->init_ops, bp->init_data, and bp->init_ops_offsets are freed via kfree() without being set to NULL . When the cleanup function bnx2x_release_f...

CVE-2026-89581 bpf, x86: Fix per-CPU address resolution into an extended register

In the Linux kernel, the following vulnerability has been resolved: bpf, x86: Fix per-CPU address resolution into an extended register The destination of the per-CPU address MOV is encoded in ModRM.reg, which is extended by REX.R, but the REX prefix is built with add1mod, which sets REX.B. REX.B...

In the Linux kernel, the following vulnerability has been resolved: bpf, x86: Fix per-CPU address resolution into an extended register The destination of the per-CPU address MOV is encoded in ModRM.reg, which is extended by REX.R, but the REX prefix is built with add1mod, which sets REX.B. REX.B...

CVE-2026-89581

A BPF x86 JIT flaw in the Linux kernel causes incorrect per-CPU address resolution when the destination is an extended register (R5–R9). The root cause is an encoding error: the REX prefix is built with add_1mod() (setting REX.B) instead of add_2mod() (setting REX.R), so the high register bit is ...

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...

CVE-2026-89574

CVE-2026-89574 is a vulnerability in the Linux kernel's device mapper (dm) array component. The root cause is insufficient validation of array block headers during read operations: array_block_check() only verifies blocknr and csum, while element_at() performs unguarded pointer arithmetic driven ...

CVE-2026-89570

A lifetime bug in the Linux kernel's CXL (Compute Express Link) MCE notifier can cause NULL dereferences and use-after-free in the MCE handler. The notifier was incorrectly registered per memory device (stored in struct cxl_memdev_state) rather than per region. The fix moves it into struct cxl_re...
