Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.58 Description: A vulnerability has been found in the Linux kernel where specific helpers with ARG PTR TO LONG,INT as arguments can write into read-only BPF maps from the BPF program side. This occurs becaus...
UBUNTU-CVE-2024-45020
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix a kernel verifier crash in stacksafe Daniel Hodges reported a kernel verifier crash when playing with sched-ext. Further investigation shows that the crash is due to invalid memory access in stacksafe. More specifically,...

DEBIAN-CVE-2024-44996
In the Linux kernel, the following vulnerability has been resolved: vsock: fix recursive -recvmsg calls After a vsock socket has been added to a BPF sockmap, its prot-recvmsg has been replaced with vsockbpfrecvmsg. Thus the following recursiion could happen: vsockbpfrecvmsg - vsockrecvmsg -...
kernel: bpf: Add BPF_PROG_TYPE_CGROUP_SKB attach type enforcement in BPF_LINK_CREATE
In the Linux kernel, the following vulnerability has been resolved: bpf: Add BPFPROGTYPECGROUPSKB attach type enforcement in BPFLINKCREATE bpfprogattach uses attachtypetoprogtype to enforce proper attach type for BPFPROGTYPECGROUPSKB. linkcreate uses bpfprogget and relies on...
kernel: bpf, sockmap: Prevent lock inversion deadlock in map delete elem
CVE-2024-35895 addresses a vulnerability in the Linux kernel's Berkeley Packet Filter BPF subsystem, specifically within the sockmap feature. The issue arises when BPF tracing programs, which can execute in various interrupt contexts, attempt to delete elements from sockmap or sockhash maps. This...
The vulnerability of the bpf component in the Linux operating system’s kernel allows a hacker to trigger a service failure.
The vulnerability of the bpf component in the Linux operating system’s kernel is related to a failure in bpfspinlock, when it is set as the value of bpftimer. This occurs because the bpfmapupdateelem call reassigns another timer object. Exploiting this vulnerability can allow an attacker to trigg...
UBUNTU-CVE-2024-43910
In the Linux kernel, the following vulnerability has been resolved: bpf: add missing checkfuncargregoff to prevent out-of-bounds memory accesses Currently, it's possible to pass in a modified CONSTPTRTODYNPTR to a global function as an argument. The adverse effects of this is that BPF helpers can...
