CVE-2026-23423

A flaw was found in the Linux kernel's btrfs file system. This vulnerability occurs in the btrfsuringreadextent function, where memory allocated for 'pages' is not properly freed when errors occur during read operations. This oversight can lead to resource exhaustion, potentially causing a Denial...
