CVE-2026-80538

A flaw was found in the XFS filesystem within the Linux kernel. The xfsrtginodeensure function incorrectly handles errors returned by xfsrtginodeload, treating I/O, allocation, or corruption errors as successful operations. This oversight can result in the realtime group inode remaining unset,...

CVE-2026-79016

A flaw was found in Google Chrome. A remote attacker could exploit an observable discrepancy in how Scalable Vector Graphics SVG are handled by crafting a malicious HTML page. This vulnerability allows the attacker to obtain sensitive cross-origin data, potentially leading to information disclosu...

K000163091: JSON processor vulnerability CVE-2026-39979

Security Advisory Description jq is a command-line JSON processor. In commits before 2f09060afab23fe9390cce7cb860b10416e1bf5f, the jvparsesized API in libjq accepts a counted buffer with an explicit length parameter, but its error-handling path formats the input buffer using %s in jvstringfmt,...

CVE-2026-80559

CVE-2026-80559 is a Linux kernel vulnerability in the sur40 input driver. The root cause is an incorrect registration ordering in sur40_probe(): input_register_device() was called before the V4L2 video device and vb2_queue were fully initialized. If userspace opened the input device immediately, ...
