CVE-2026-80904

CVE-2026-80904 is a Linux kernel vulnerability in the net/tls (TLS offload) subsystem. When an asynchronous TLS decryption fails, tls_sw_recvmsg() and tls_sw_read_sock() correctly check async_wait.err and abort the read, but tls_sw_splice_read() performs no such check. As a result, a splice opera...

CVE-2026-80852

CVE-2026-80852 is an out-of-bounds write in the Linux kernel's TLS device offload path (net/tls/tls_device.c). The root cause is that tls_push_data() skips its fragment-count check on an early MSG_MORE break, allowing num_frags to exceed MAX_SKB_FRAGS (17) when splice(SPLICE_F_MORE) calls are iss...

COPY-FAIL-CVE-2026-31431

This is a public Proof-of-Concept PoC for CVE-2026-31431 "Copy Fail", a Linux kernel local privilege escalation vulnerability CVSS 7.8 affecting most major distributions since 2017. It corrupts the page cache of a setuid binary like /usr/bin/su using the kernel's AFALG crypto API + splice, allowi...

SUSE CVE-2026-74631

In the Linux kernel, the following vulnerability has been resolved: net: smc: fix splice entry lifetime imbalance in smcrxsplice smcrxsplice passes pages to splicetopipe before taking the references that cover the lifetime of each splice entry. In the VM-backed RMB path, splicetopipe may drop...

CVE-2026-74631

A flaw was found in the Linux kernel's smcrxsplice function within the net: smc component. This vulnerability arises from an imbalance in the lifetime management of splice entries, where page references are not properly handled before being passed to splicetopipe. This can lead to a reference cou...
