Threats tagged 'cve-2026-43163'

SUSE Linux Enterprise 15 SP6 kernel received a security update addressing multiple vulnerabilities across various kernel subsystems including networking, timers, bonding, BPF, DRM, SCSI, Bluetooth, and others. The update fixes issues such as memory leaks, use-after-free bugs, type confusion, out-of-bounds writes, and race conditions. These fixes collectively improve the security and stability of the kernel.

A security update for the SUSE Linux Enterprise 16.0 kernel addresses numerous vulnerabilities across various kernel subsystems. The fixes cover a wide range of issues including use-after-free, race conditions, NULL pointer dereferences, and logic errors affecting components such as timers, filesystems, networking, SCSI, and security modules like AppArmor. These vulnerabilities could allow local attackers to cause denial of service, escalate privileges, or expose sensitive information. The update is confirmed to fix these issues and is available for affected kernel versions.
