Denial of Service

This is a null pointer dereference vulnerability in the Linux kernel's GFS2 (Global File System 2) subsystem that occurs during the log flush operation when a race condition exists between glock work and filesystem unmount. An unprivileged local attacker can trigger this vulnerability to cause a kernel panic and denial of service by timing glock operations to race with unmount, exploiting the fact that sdp->sd_jdesc is dereferenced without null checks. The vulnerability has patches available from the Linux kernel development team across multiple stable branches, and while the EPSS score is very low (0.05%), the impact is a complete system availability disruption through kernel crash.

A denial-of-service vulnerability exists in the Linux kernel's MLX5 network driver switchdev mode implementation, caused by a problematic commit (662404b24a4c4d839839ed25e3097571f5938b9b) that was reverted due to suspected instability and system crashes. Local attackers with low privileges can trigger this vulnerability to cause system unavailability or kernel crashes without user interaction. The vulnerability affects Linux kernel versions 6.3 through 6.8-rc1, with an EPSS score of 0.02% indicating low exploitation probability in the wild, though patches are available from the kernel maintainers.

A memory management flaw exists in the Linux kernel's framebuffer console (fbcon) font handling code where system fonts fail to be restored to their previous state when a vc_resize() operation fails during fbcon_do_set_font().
