CVE-2026-68444

The CVE-2026-68444 affects the Linux kernel’s firmware/arm_ffa path. The vulnerability arises in ffa_partition_info_get(), which passes uuid_str directly to uuid_parse() without a NULL check. If a caller provides NULL, uuid_parse() dereferences the NULL, leading to a kernel panic. The fix adds a ...

CVE-2026-68243

A flaw was found in the drm/i915/gem component of the Linux kernel. A local attacker could trigger a NULL dereference by setting a context engine slot to an invalid class and then attempting to apply specific parameters to that slot. This could lead to a system crash, resulting in a Denial of...

CVE-2026-68306

A flaw was found in the Linux kernel's Wi-Fi subsystem, specifically within the mt76 driver for MediaTek mt7996 devices. This vulnerability occurs because the mt76connacgetehtphycap routine can return a NULL pointer, which is not properly checked before being dereferenced. An attacker could...

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Return NULL on error in activeinstance Avoid returning &node-base when node is NULL due to OOM during GFPATOMIC allocation. Discovered using AI-assisted static analysis confirmed by Intel Product Security. cherry picked...

UBUNTU-CVE-2026-68337

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject redirect helpers without a bpfnetcontext The bpfredirect helpers and skbdoredirect obtain the per-task bpfredirectinfo via bpfnetctxgetri, which dereferences the current-bpfnetcontext unconditionally. That context is...

In the Linux kernel, the following vulnerability has been resolved: bonding: fix devconfall NULL dereference when IPv6 is disabled When booting with the 'ipv6.disable=1' parameter, the devconfall is never initialized because inet6init exits before addrconfinit is called which initializes it...

UBUNTU-CVE-2026-68186

In the Linux kernel, the following vulnerability has been resolved: binfmtmisc: set haveexecfd only once the interpreter is opened loadmiscbinary raises bprm-haveexecfd as soon as it sees the 'O' or 'C' flag. This happens well before it opens the interpreter. If that open fails the flag stays set...

CVE-2026-68261

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: fix error checking of pvrvmcontextlookup Since pvrvmcontextlookup returns either NULL or a pointer, then stop using ISERR for checking the return value. Using ISERR leads to the kernel oops reported below. It can...
