CVE-2026-45838
In the Linux kernel, the following vulnerability has been resolved: bpf: fix end-of-list detection in cgroupstoragegetnextkey listnextentry never returns NULL -- when the current element is the last entry it wraps to the list head via containerof. The subsequent NULL check is therefore dead code...
CVE-2026-45967
In the Linux kernel, the following vulnerability has been resolved: bpf: Return proper address for non-zero offsets in insn array The mapdirectvalueaddr function of the instruction array map incorrectly adds offset to the resulting address. This is a bug, because later the resolvepseudoldimm64...
Linux kernel 安全漏洞
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from bpfmapgetinfobyfd function in bpf. This function does not check the frozen state of maps during t...
Linux kernel 安全漏洞
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from not restricting the size of BPF program signatures. This vulnerability may cause the kernel to...
CVE-2026-45951
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix a potential use-after-free of BTF object Refcounting in the checkpseudobtfid function is incorrect: the checkpseudobtfid function might get called with a zero refcounted btf. Fix this, and patch related code accordingly...
PT-2026-43818
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists in the BPF subsystem involving BTF objects. The problem stems from incorrect refcounting within the check pseudo btf id function, which can lead to the chec...
Linux kernel 安全漏洞
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the synclinked regs function in bpf. When this function copies the id of knownreg, it may cause a...
[SECURITY] Fedora 44 Update: bind-9.18.49-1.fc44
BIND Berkeley Internet Name Domain is an implementation of the DNS Domain Name System protocols. BIND includes a DNS server named, which resolves host names to IP addresses; a resolver library routines for applications to use when interfacing with DNS; and tools for verifying that the DNS server ...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: bpf: Defer work in bpftimercancelandfree Currently, the same issue as in the previous patch two timer callbacks trying to cancel each other can also occur when using bpfmapupdateelem. More precisely, freeing elements containing...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: bpf: Programs marked as sleepable in the kprobe.multi configuration are rejected during attachment. kprobe.multi programs run in atomic/RCU contexts and cannot sleep. However, the bpfkprobemultilinkattach function did not validat...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: powerpc/bpf: Fixed the JIT code size calculation for the BPF trampoline. The archbpftrampolinesize function provides the JIT size of the BPF trampoline before the buffer for JIT compilation of it is allocated. The total number of...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: BPF: Fixed incorrect pruning due to atomic fetch precision tracking When backtrackinsn encounters a BPFSTX instruction with BPFATOMIC and BPFFETCH, the src register or r0 for BPFCMPXCHG also acts as a destination, thereby receivi...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: BPF: Fixed the verifier’s assumptions regarding the socket-sk structure. The verifier assumes that the sk field in the struct socket structure is valid and not NULL when the socket pointer itself is trusted and not NULL. This...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: bpf: Do not report a verification bug for missing bpfsccvisit calls on speculative execution paths. Syzbot generated a program that triggers a verifierbug call in maybeexitscc. maybeexitscc assumes that, when called for a state...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed the exclusive map memory leak When exclproghash is 0 and exclproghashsize is non-zero, the map also needs to be freed. Otherwise, the map memory will not be reclaimed, similar to the memory leak issue reported by syzbo...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: No support for struct arguments in trampoline programs The current implementation does not support struct arguments. This causes an oops when running the bpf selftest: $ ./testprogs -a tracingstruct Oops1: CPU -1...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: powerpc/bpf: Fixed the detection of BPF atomic instructions. The commit 91c960b0056672 “bpf: Rename BPFXADD and prepare to encode other atomic instructions in .imm” changed BPFXADD to BPFATOMIC and added a mechanism to...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix for constant blinding in PROBEMEM32 stores The immediate stores of BPFST|BPFMEM32 are not handled by bpfjitblindinsn. This allows user-controlled 32-bit immediate values to survive blinding and be included in JIT-compile...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: bpf: Consider the return from setmemoryrox when using bpfjitbinarylockro. setmemoryrox may fail, leaving memory unprotected. Check the return value and bail out if bpfjitbinarylockro returns an error...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: libbpf: Null-pointer dereferencing is prevented when the program to be loaded does not have a BTF. In bpfobjecloadprog, there is no guarantee that obj-btf is not NULL when it is passed to btffd. This function does not perform any...
