CVE-2026-52961

A flaw was found in the Linux kernel's Ceph filesystem component. A race condition exists in the cephbuildxattrsblob function where the required extended attribute xattr blob size is computed before the buildxattrs call. During this window, another process can update the xattr blob, leading to a...

CVE-2026-53059

A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Validate cpuid against nrcpuids in DMAH alloc The cpuid attribute supplied by user space through UVERBSATTRALLOCDMAHCPUID is passed directly to cpumasktestcpu without first verifying that the value is within the valid...

CVE-2026-53166

The CVE-2026-53166 issue concerns the Linux kernel futex (Fast Userspace Mutex) requeue path, where a non-top waiter that already owns a PI futex could trigger a NULL pointer dereference in remove_waiter() during self-deadlock, causing a kernel crash/DoS. Public sources describe the vulnerability...

CVE-2026-53111

CVE-2026-53111 is a Linux kernel issue where bpf_lwt_xmit_push_encap dereferences skb_dst(skb)->dev during test_run when skb->_skb_refdst is uninitialized, leading to a kernel crash. A patch and remediation include initializing skb->_skb_refdst before bpf_test_run_skb, as evidenced by Ro...

CVE-2026-52961

The CVE-2026-52961 entry describes a race in the Linux kernel Ceph xattr handling. Root cause: during __build_xattrs_blob(), the required_blob_size computation happens before __build_xattrs(), while __build_xattrs() may release and reacquire i_ceph_lock, allowing a newer MDS-provided blob to repl...
