CVE-2026-74337

A flaw was found in the Linux kernel, specifically within the BPF Berkeley Packet Filter subsystem. This vulnerability allows NMI Non-Maskable Interrupt and tracepoint BPF programs to re-enter certain internal locks, known as LRU Least Recently Used locks, while they are already held. This re-ent...

CVE-2026-74258

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. A missing bounds check when accessing user space data for uprobemulti could allow a local attacker to read or write to memory outside of intended boundaries. This vulnerability can lead to information disclosure or...

CVE-2026-74354

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. A local attacker could exploit a locking issue within the zappages function. This vulnerability arises because zapvmarange requires a specific memory map lock mmaplock that, when acquired under certain conditions, can le...

CVE-2026-74314

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. This vulnerability arises from improper handling of special fields during the recycling of map values, which can lead to unsafe destruction operations. Specifically, in tracing programs operating within a Non-Maskable...

CVE-2026-72426

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. The cleanfuncstate function, which manages stack slot cleanup, incorrectly clears metadata for pointer spills. This allows a subsequent read from a partially live stack slot to bypass crucial non-scalar register-fill...

UBUNTU-CVE-2026-74258

In the Linux kernel, the following vulnerability has been resolved: bpf: Guard getuser acesss with accessok for uprobemulti data As reported by sashiko 1 we need to use accessok to check the user space data bounds before we use get-user to get it. 1...

PT-2026-72299

In the Linux kernel, the following vulnerability has been resolved: bpf,fork: wipe -bpf storage before bailouts that access it Currently, copy process can bail out to free task before p-bpf storage has been initialized, with this call graph shown here for the !CONFIG MEMCG case: copy process dup...

USN-8604-1: Linux kernel (Azure) vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - Foo-over-UDP FOU; - ARM64 architecture; - x86 architecture; - Block layer subsystem; - Cryptographic API; - Drivers...

CVE-2026-63809

CVE-2026-63809 affects the Linux kernel memory-management path used by BPF when handling proc sysctl writes. The vulnerability stems from proc_sys_call_handler() allocating a temporary sysctl buffer with kvzalloc() and passing it to __cgroup_bpf_run_filter_sysctl(); since kvzalloc() may fall back...

CVE-2026-53084

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability involves a lock ordering problem that occurs when BPF programs acquire certain locks that depend on the mmaplock. This issue could potentially lead to system instability or unexpected behavior due to...

SUSE CVE-2026-53032

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix NULL deref in mapkptrmatchtype for scalar regs Commit ab6c637ad027 "bpf: Fix a bpfkptrxchg issue with local kptr" refactored mapkptrmatchtype to branch on btfiskernel before checking basetype. A scalar register stored in...

CVE-2026-53031

A flaw was found in the Linux kernel. The arenaallocpages function within the Berkeley Packet Filter BPF subsystem does not properly validate the nodeid parameter. A local attacker could exploit this vulnerability by supplying an invalid nodeid, which is then used without bounds checking during...

CVE-2026-45951

A flaw was found in the Linux kernel, specifically within its BPF Berkeley Packet Filter subsystem. This vulnerability, a use-after-free, arises from incorrect reference counting in the checkpseudobtfid function. It allows a local attacker to potentially corrupt memory, which could lead to...
