CVE-2026-43367

A flaw was found in the Linux kernel's drm/amd component. This vulnerability allows a local attacker to cause a Denial of Service DoS by triggering a NULL pointer dereference during device cleanup on unsupported hardware. This can lead to system instability or a crash, impacting the availability ...

CVE-2026-43364

A flaw was found in the Linux kernel's ublk subsystem. A local user can trigger a NULL pointer dereference by sending an UPDATESIZE command to a ublk device that has been added but not yet started, or one that has been stopped. This occurs due to insufficient state validation before dereferencing...

gitsign --verify panics on empty-certificate PKCS7 and exits 0, bypassing exit-code callers

Summary CertVerifier.Verify in pkg/git/verifier.go unconditionally dereferences certs0 after sd.GetCertificates without checking the slice length. A CMS/PKCS7 signed message with an empty certificate set is a structurally valid DER payload; GetCertificates returns an empty slice with no error,...
