CVE-2026-23342
A flaw was found in the Linux kernel. On systems configured with PREEMPTRT, a race condition exists within the Berkeley Packet Filter BPF cpumap functionality. This flaw allows a local attacker to trigger concurrent access to the xdpbulkqueue. Successful exploitation can lead to a kernel crash,...
EUVD-2026-15378
In the Linux kernel, the following vulnerability has been resolved: bpf, arm64: Force 8-byte alignment for JIT buffer to prevent atomic tearing struct bpfplt contains a u64 target field. Currently, the BPF JIT allocator requests an alignment of 4 bytes sizeofu32 for the JIT buffer. Because the ba...
EUVD-2026-15309
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix race in cpumap on PREEMPTRT On PREEMPTRT kernels, the per-CPU xdpbulkqueue bq can be accessed concurrently by multiple preemptible tasks on the same CPU. The original code assumes bqenqueue and cpumapflush run atomically...

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix stack-out-of-bounds write in devmap getupperifindexes iterates over all upper devices and writes their indices into an array without checking bounds. Also the callers assume that the max number of upper devices is...
EUVD-2026-15269
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix a UAF issue in bpftrampolinelinkcgroupshim The root cause of this bug is that when 'bpflinkput' reduces the refcount of 'shimlink-link.link' to zero, the resource is considered released but may still be referenced via...
