CVE-2026-74685

A flaw was found in the Linux kernel's hwmon subsystem, specifically within the ltc4282 driver. When a negative value is passed to the ltc4282writecurr function, an incorrect type cast converts this input into a large positive value. This leads to an integer overflow, causing the current limit to...

CVE-2026-74711

A flaw was found in the Linux kernel's hardware monitoring hwmon subsystem, specifically within the Power Management Bus pmbus driver. This vulnerability arises from a type confusion issue where the system incorrectly interprets data types during notification processing. An attacker could exploit...

CVE-2026-74671

A flaw was found in the Linux kernel's Integrity Measurement Architecture IMA subsystem. The xattrverify function, which verifies extended attributes, incorrectly mixes int and sizet data types in its digest-length check. This can lead to an integer underflow when processing a truncated extended...

CVE-2026-74646

A flaw was found in the Linux kernel's fastrpc subsystem. When an invoke operation is interrupted by a signal, the fastrpcinternalinvoke function moves memory mappings without properly holding the fl-lock. This missing lock during memory map manipulation creates a race condition, which could lead...
