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...

CVE-2026-43486

A flaw was found in the Linux kernel. The contpteptepsetaccessflags function, responsible for managing contiguous page table entries CONT PTEs on ARM64 architectures, incorrectly determines when an access flag update is a no-op. This can occur when a sibling page table entry's dirty bit causes th...

The vulnerability of the libpng library lies in the lack of checks for an adequate number of input pixels. This allows attackers to exploit the system to disclose protected information and perform denial-of-service attacks.

The vulnerability of the libpng library lies in the lack of checks for a sufficient number of input pixels during the processing of the last partial portion of the palette extension in the ARM/AArch64 Neon optimization path. Exploiting this vulnerability can allow an attacker to disclose sensitiv...
