CVE-2026-74483

A flaw was found in the binfmtmisc component of the Linux kernel. An unprivileged local attacker, operating under specific memory constraints a tight memory cgroup, could repeatedly trigger a failure in the bmfillsuper function during a mount operation. This failure prevents the proper release of...

kernel: sched/psi: fix race between file release and pressure write

A flaw was found in the Linux kernel's Pressure Stall Information PSI subsystem. A race condition exists between the file release and pressure write operations, specifically concerning the priv member of struct kernfsopenfile. This can lead to a use-after-free vulnerability or a NULL dereference,...

CVE-2026-74305

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability allows a program without cgroup storage to bypass compatibility checks when bridging tail call chains. This could enable unintended interactions between programs with and without cgroup storage,...

CVE-2026-72010

A flaw was found in the Linux kernel's cgroup/cpuset component. A local user can exploit this by configuring a child cpuset without explicitly setting its memory nodes. When a CPU hotplug event occurs, a division-by-zero error is triggered during memory policy rebind, leading to a system crash...

CVE-2026-72213

A flaw was found in the Linux kernel's huge page memory management hugetlb. A mismatch in how reserved and non-reserved huge page control group cgroup charges are handled during memory allocation and deallocation can lead to an incorrect cgroup being uncharged. This issue results in a page counte...

CVE-2026-72427

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter cgroup program handling. Incorrect indexing in the replaceeffectiveprog and purgeeffectiveprogs functions, particularly when BPFFPREORDER programs are active, can lead to memory corruption. This issue can result in overwriting...

Linux Distros Unpatched Vulnerability : CVE-2026-74305

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - bpf: Tighten cgroup storage cookie checks for prog arrays The fix in commit abad3d0bad72 bpf: Fix oob access in cgroup local storage is still incomplete. The...

UBUNTU-CVE-2026-74483

In the Linux kernel, the following vulnerability has been resolved: binfmtmisc: don't leak the user namespace when the mount fails bmgettree takes a reference to the user namespace and hands it to gettreekeyed as the sget key. sgetfc moves that reference into sb-sfsinfo and clears fc-sfsinfo, so...

CVE-2026-74371

In the Linux kernel, the following vulnerability has been resolved: bpf: fix BPFPROGQUERY OOB write and cgroup backward compat BPFPROGQUERY writes back the 'query.revision' field unconditionally to userspace. If userspace passes a smaller 'bpfattr' structure e.g. 40 bytes, which was the layout...

CVE-2026-74342

In the Linux kernel, the following vulnerability has been resolved: kernfs: link kn to its parent before the LSM init hook After commit 12e9e3cd03b5 "simpexattr: use per-sb cache", kernfsxattrset and kernfsxattrget compute the cache via kernfsrootkn before any other check. kernfsrootkn walks...

CVE-2026-74338

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject sleepable BPFLSMCGROUP programs at load time The cgroup shim runs under rcureadlockdontmigrate, so we should not attach any sleepable BPF programs there. Add support to the verifier to explicitly reject attempts to lo...
