Astra Linux – Vulnerabilities in Linux-6.1, Linux-5.15, Linux-5.10

In the Linux kernel, the following vulnerability has been resolved: arm64: bpf: Mitigation is only applied to cBPF programs loaded by unprivileged users. Support for eBPF programs loaded by unprivileged users is typically disabled. This means that only cBPF programs need to be mitigated for BHB...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: bpf: Prevent “decltag” from being referenced in “funcproto” arguments. Syzkaller managed to encounter another issue with “decltag”: btffuncprotocheck kernel/bpf/btf.c:4506 inline btfcheckalltypes kernel/bpf/btf.c:4734 inline...

Astra Linux – Vulnerability in Linux

In kernel/bpf/verifier.c in the Linux kernel before version 5.12.13, a branch prediction can be mispredicted e.g., due to type confusion, allowing a non-privileged BPF program to access arbitrary memory locations through a side-channel attack, known as CID-9183671af6db...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: bpf: Fixed the WARN function in getbpfrawtp regs. syzkaller reported an issue: WARNING: CPU: 3 PID: 5971 at kernel/trace/bpftrace.c:1861 getbpfrawtp regs+0xa4/0x100 kernel/trace/bpftrace.c:1861 Modules linked in: CPU: 3 UID: 0...

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix for checking attempts to corrupt spilled pointers When a register is spilled onto a stack as a 1/2/4-byte register, we set slottypeBPFREGSIZE - 1 plus possibly a few more bytes below it, depending on the actual spill siz...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Rejects redirects of skmsg messages to non-TCP sockets With a SOCKMAP/SOCKHASH map and a skmsg program, users can direct messages sent from one TCP socket s1 to actually exiting from another TCP socket s2...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed the metadatadst leak in bpfredirectneigh for arguments bpfredirectneighv4,6 Cilium includes a BPF egress gateway feature that forces outgoing Kubernetes Pods’ traffic to pass through dedicated egress gateways. This...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Fixed the jump offset calculation in tailcall. The additional call to bpfintjitcompile skips the JIT context initialization. This effectively skips the offset calculation, resulting in outoffset = -1. Therefore, t...

Astra Linux – Vulnerability in Linux, Linux 5.10

preallocelemsandfreelist in kernel/bpf/stackmap.c in the Linux kernel before version 5.14.12 allows unprivileged users to trigger an eBPF multiplication integer overflow, resulting in an out-of-bounds write...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed out-of-bounds access in cgroup local storage Lonial reported that an out-of-bounds access in cgroup local storage can occur through tail calls. This occurs when two programs each utilize a cgroup local storage with...

Astra Linux – Vulnerability in 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...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: bpf: Fixed the memory leak in bpfskselectreuseport As pointed out in the original comment, a lookup in sockmap can return a TCP ESTABLISHED socket. Such a TCP socket may have had SOATTACHREUSEPORTEBPF set before it became...

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

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...
