CVE-2024-26676 af_unix: Call kfree_skb() for dead unix_(sk)->oob_skb in GC.

In the Linux kernel, the following vulnerability has been resolved: afunix: Call kfreeskb for dead unixsk-oobskb in GC. syzbot reported a warning 0 in unixgc with a repro, which creates a socketpair and sends one socket's fd to itself using the peer. socketpairAFUNIX, SOCKSTREAM, 0, 3, 4 = 0...

CVE-2024-26676

CVE-2024-26676 concerns the Linux kernel’s af_unix garbage collection. The issue arose when a socketpair self-send creates a self-referential GC candidate cycle that is not untangled due to missing MSG_OOB handling, causing a memory leak. The root cause was exposed after removing io_uring GC dead...

CVE-2024-26643

CVE-2024-26643 is a Linux kernel vulnerability in netfilter nf_tables where the asynchronous rhashtable garbage-collection can race with the release of anonymous sets that have timeouts, leading to a potential collection of elements during commit path teardown. The root cause is a race between se...

BIT-GOLANG-2023-29404 Improper handling of non-optional LDFLAGS in go command with cgo in cmd/go

The go command may execute arbitrary code at build time when using cgo. This may occur when running "go get" on a malicious module, or when running any other command which builds untrusted code. This is can by triggered by linker flags, specified via a "cgo LDFLAGS" directive. The arguments for a...

CVE-2023-52581

A use-after-free flaw was found in the Linux kernel’s nftables sub-component due to a race problem between the set GC and transaction in the Linux Kernel. This flaw allows a local attacker to crash the system. This flaw is similar to the previous CVE-2023-4244 but for a different part of the sour...
