CVE-2026-9728

CVE-2026-9728 is a time-of-check/time-of-use (TOCTOU) race condition in the Zephyr RTOS userspace mailbox subsystem. The syscall verifier z_vrfy_mbox_send() in drivers/mbox/mbox_handlers.c validates msg->data/msg->size by reading them directly from live userspace memory, then forwards the o...

CVE-2026-9728 TOCTOU race in mbox_send syscall verifier allows userspace to leak kernel memory

The userspace syscall verifier zvrfymboxsend in drivers/mbox/mboxhandlers.c validated the nested msg-data/msg-size fields by reading them directly out of live userspace memory, and then forwarded the original, still-mutable userspace struct mboxmsg pointer to zimplmboxsend and the underlying...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bpf: Guard conntrack opts error writes The conntrack lookup and allocation functions take an opts pointer along with an optssz argument. The verifier only checks the memory range described by optssz, but the wrappers...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: BPF: Resetting the register bounds before narrowing the RETVAL range in checkmemaccess When the BPF verifier processes a context load of an LSM hook return value, it calls markregs32range to narrow the register to the hook’s vali...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bpf: Rejects negative constant offsets for buffer pointers The verifier now rejects accesses to variables with offsets of type PTRTOTPBUFFER and PTRTOBUF, but it still accepts constant negative offsets generated by pointer...

Astra Linux – Vulnerability in Linux

A issue was discovered in the Linux kernel through version 5.11.x. The kernel/bpf/verifier.c file contains unwanted out-of-bounds speculation during pointer arithmetic operations, which allows for side-channel attacks that circumvent Spectre mitigations and extract sensitive information from kern...

CVE-2026-74720

CVE-2026-74720 affects the BPF component of the Linux kernel . In adjust_ptr_min_max_vals(), handling of the commuted arithmetic operation scalar += pointer copies only selected fields from the source pointer state to the destination register. Because pointer provenance is tracked across multiple...

CVE-2026-72401

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. This vulnerability occurs when the bpfcheck function fails to allocate certain resources, leading to a memory leak of insnauxdata. An attacker could potentially exploit this by repeatedly triggering the flaw, which may...
