CVE-2026-53200

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Fix handling of XN0 when !FEATXNX XN has already been extracted from its bitfield position so using FIELDPREP on the mask that clears XN0 is completely broken, having the effect of unconditionally granting execute...

CVE-2026-53200

The CVE refers to the Linux kernel KVM on ARM64 where the XN bit handling was broken when FEAT_XNX is not enabled. Specifically, a FIELD_PREP() mask used to clear XN[0] manipulated the wrong bit, unconditionally granting execute permissions. The issue is resolved by correcting the bit manipulatio...

CVE-2026-53036

The CVE-2026-53036 issue concerns the Linux kernel BPF JIT on ARM64. check_imm(bits, imm) erroneously allowed a signed N-bit range of [-2^N, 2^N), effectively giving an (N+1)-bit range, which permits values in [2^18, 2^19) for imm19 (and similarly for imm26) to slip through. This caused potential...

libpng: libpng: Information disclosure and denial of service via out-of-bounds read/write in Neon palette expansion

A flaw was found in libpng. A remote attacker could exploit an out-of-bounds read and write vulnerability in the ARM/AArch64 Neon-optimized palette expansion path. This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to...
