Astra Linux - уязвимость в linux-5.10

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 - уязвимость в abseil

There exists a heap buffer overflow vulnerability in Abseil-cpp. The constructor methods reserve and rehash, which are used to manage the size of the container’s backing store, do not impose an upper limit on the size of these methods’ arguments. As a result, a caller could pass a very large size...

CVE-2025-68744

CVE-2025-68744 is a Linux kernel vulnerability affecting BPF maps. The issue arises from not freeing memory for BPF_KPTR_{REF,PERCPU} fields when updating certain lru_percpu_hash maps, potentially causing references to remain after map destruction. The root cause, as described in the initial CVE ...

kernel: kernel: Denial of Service via memory leak in LRU hash maps

A flaw was found in the Linux kernel. A local user could exploit a memory leak vulnerability in the Least Recently Used LRU and LRUPERCPU hash maps. This occurs when the kernel allocates a new element during a map update but fails to release it if the hash table bucket cannot be locked. Repeated...
