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...

CVE-2026-68295

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Zero-extend signed ALU32 div/mod results ALU32 operations write a 32-bit result and leave the upper 32 bits of the BPF register zero. The LoongArch JIT sign-extends the result of signed ALU32 BPFDIV and BPFMOD...

CVE-2026-68295 LoongArch: BPF: Zero-extend signed ALU32 div/mod results

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Zero-extend signed ALU32 div/mod results ALU32 operations write a 32-bit result and leave the upper 32 bits of the BPF register zero. The LoongArch JIT sign-extends the result of signed ALU32 BPFDIV and BPFMOD...

CVE-2026-68295

In the Linux kernel, LoongArch BPF ALU32 division/modulo results were sign-extended in the JIT, causing upper 32 bits to be set while verifier/interpreter assume zero-extension. The issue arises when signed ALU32 BPF_DIV/BPF_MOD (off=1) produce a negative quotient/remainder, leaving bits 63:32 se...

EUVD-2026-55396

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Zero-extend signed ALU32 div/mod results ALU32 operations write a 32-bit result and leave the upper 32 bits of the BPF register zero. The LoongArch JIT sign-extends the result of signed ALU32 BPFDIV and BPFMOD...

CVE-2026-68285

The CVE concerns LoongArch BPF in the Linux kernel. Root cause: during JIT compilation, bpf_int_jit_compile() may return early on the first pass, leaving ctx->offset alive; if a later subprogram fails, bpf_jit_free() does not free jit_data->ctx.offset, causing a memory leak of the JIT conte...

CVE-2026-68285 LoongArch: BPF: Fix memory leak in bpf_jit_free()

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Fix memory leak in bpfjitfree When bpfintjitcompile is called for subprograms, it returns early during the first pass !prog-isfunc || extrapass is false, keeping ctx-offset alive for the subsequent extra pass. If...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Enabling exception fixup for specific ADE subcodes This patch enables the LoongArch BPF JIT to handle recoverable memory access errors generated by BPFPROBEMEM instructions. When a BPF program performs memory access...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: BPF: Narrow access to the pointer ctx fields is now rejected. The following BPF program, simplified from a syzkaller repro, causes a kernel warning: c r0 = u8 r1 + 169; exit; Here, the pointer field sk is located at offset 168 in...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: BPF: Freeing special fields when updating lru,percpuhash maps Since lru,percpuhash maps support BPFKPTRREF,PERCPU, missing calls to ‘bpfobjfreefields’ in ‘pcpucopyvalue’ could cause the memory referenced by BPFKPTRREF,PERCPU fiel...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: In the bpf and arm64 architectures, there is a vulnerability where forced 8-byte alignment of the JIT buffer is required to prevent atomic tearing. The struct bpfplt structure contains a u64 target field. Currently, the BPF JIT...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Ensuring that pending IRQ work is processed before freeing the ring buffer. A race condition was addressed in this fix, where irqwork could be queued in bpfringbufcommit, but the ring buffer was freed before the work execute...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Check skb-transportheader is set in bpfskbcheckmtu. The bpfskbcheckmtu helper needs to use skb-transportheader when the BPFMTUCHKSEGS flag is used: bpfskbcheckmtuskb, ifindex, &mtulen, 0, BPFMTUCHKSEGS. The transportheader i...

CVE-2026-64575

A flaw was found in the Linux kernel. A double release of socket resources can occur during batch reallocation in the BPF Berkeley Packet Filter TCP iterator. A local attacker could exploit this vulnerability to trigger a kernel panic. This leads to a system crash, resulting in a Denial of Servic...

CVE-2026-64575

In the Linux kernel, the following vulnerability has been resolved: bpf: tcp: fix double sock release on batch realloc bpfitertcpbatch releases the current batch via bpfitertcpputbatch, which drops the socket refs and rewrites each slot with the socket cookie, then grows the batch. cursk/endsk ar...

CVE-2026-64575

CVE-2026-64575 affects the Linux kernel’s BPF TCP iterator. The issue is a double release of socket resources during batch reallocation in bpf_iter_tcp_batch, where on realloc failure the code returns ERR_PTR() and leaves cur_sk

CVE-2026-64507

A flaw was found in the Linux kernel. This vulnerability involves an incomplete defense against Spectre-v2, a type of attack that can expose sensitive information by exploiting how modern processors predict future operations. Specifically, when the Berkeley Packet Filter BPF Just-In-Time JIT...

CVE-2026-64352

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. When certain security modules interact with network routing tables, it can trigger diagnostic warnings. This issue primarily affects debug kernels by generating console messages and does not lead to direct security...

CVE-2026-64355

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter devmap feature. When handling devmap broadcast redirects, fragmented network frames are not properly managed during the cloning process. This can lead to an out-of-bounds access, where the system attempts to read or write data beyo...
