CVE-2026-97474

The Linux kernel contains a vulnerability in the wifi: iwlwifi: mld component that causes a kernel panic during a reconfiguration failure. The root cause is a use-after-free condition: when a firmware (FW) error occurs during reconfiguration, mac80211 frees BSS connection links but fails to notif...

EUVD-2026-86054

In the Linux kernel, the following vulnerability has been resolved: ata: ahci: fail probe if BAR too small for claimed ports When an AHCI controller is disabled in BIOS, its HOSTCAP register may contain a bogus value, e.g. 0xFFFFFFFF. Since CAP.NP Number of Ports is a zeroes based 5-bit register...

CVE-2026-93815

A vulnerability exists in the Linux kernel involving the au1000 driver. The au1000_close() function incorrectly calls free_irq() while holding the aup->lock spinlock. Because free_irq() can sleep while acquiring the desc->request_mutex , this violates kernel locking rules and triggers a Loc...

CVE-2026-93813

The Linux kernel contains a vulnerability in the btrfs file system where a crafted image with a corrupted INODE_REF item can trigger an out-of-boundary access. This occurs because the namelen can exceed the BTRFS_NAME_LEN limit of 255, while the allocated memory for @name remains only 255 bytes. ...
