SUSE CVE-2026-23383

In the Linux kernel, the following vulnerability has been resolved: bpf, arm64: Force 8-byte alignment for JIT buffer to prevent atomic tearing struct bpfplt contains a u64 target field. Currently, the BPF JIT allocator requests an alignment of 4 bytes sizeofu32 for the JIT buffer. Because the ba...

CVE-2026-23383

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter JIT Just-In-Time compiler on arm64 architectures. The BPF JIT allocator incorrectly requests a 4-byte alignment for its buffer, while a critical target field within the bpfplt structure requires 8-byte alignment. This misalignment...

CVE-2026-23345

A flaw was found in the Linux kernel. When the FEATLPA2 feature is enabled on ARM64 systems, the kernel incorrectly handles the PTESHARED bits in Graphics Control System GCS memory mappings. This misconfiguration can lead to a kernel paging request and subsequently a system panic, resulting in a...

CVE-2026-23316

A flaw was found in the Linux kernel's handling of multipath hash seeds on ARM64 architectures. This vulnerability can lead to a system crash kernel panic when the kernel is compiled with specific optimizations, such as Clang with Link-Time Optimization LTO, due to an alignment fault during memor...

CVE-2026-23383

CVE-2026-23383 affects the Linux kernel’s BPF JIT path on arm64. The root cause was 4-byte alignment in bpf_jit_binary_pack_alloc() causing the JIT buffer’s base to be only 4-byte aligned, which could misalign the 64-bit target field in struct bpf_plt. Consequences include UBSAN misaligned-access...
