CVE-2026-90312

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF. This vulnerability arises from an issue in how the BPF verifier processes certain memory load operations, specifically when a load-acquire instruction fetches into its own source register. This can lead to a type confusion, where...

CVE-2026-93111

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF tracing mechanism. This vulnerability occurs when tracingmulti links are not properly managed, specifically when they fail to release resources after being attached alongside fentry links. This improper resource handling can lead t...

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

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 depending on the actual spill size...

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 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 5.10

In the Linux kernel, the following vulnerability has been resolved: BPF: Use VMMAP instead of VMALLOC for the ringbuf area. After the commit 2fd3fb0be1d1 “KASAN, vmalloc: Unpoison VMALLOC pages after mapping”, non-VMALLOC mappings will be marked as accessible in getvmareanode when KASAN is enable...

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 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 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 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...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed incorrect reg type conversion in releasereference Some helper functions will allocate memory. To avoid memory leaks, the verifier requires the eBPF program to release this memory by calling the corresponding helper...

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

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...

CVE-2026-98062

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. The kernel incorrectly treats certain signal tracepoint arguments as trusted memory pointers, even when special non-pointer indicator values are passed during signal delivery. A local user with privileges to attach BPF...

CVE-2026-98043

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. The verifier incorrectly assumes that certain pointer types are non-null without accounting for unbounded offsets that can wrap around to zero at runtime. A local user with permissions to load BPF programs can exploit thi...

CVE-2026-98041

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. The verifier incorrectly predicts that 32-bit conditional branch comparisons between a pointer and zero are always taken, failing to account for valid pointer values whose lower 32 bits can be zero. A local attacker could...

CVE-2026-98040

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. When validating conditional jump operations using register comparisons against null values, the verifier fails to properly track register precision across different execution paths. A local user capable of loading BPF...
