CopyFail-CVE-2026-31431

CopyFail: CVE-2026-31431 Python implementation of copy.fail. Overwrites the page cache of a setuid-root binary via AFALG + splice to get root. No race, no offsets works on any Linux distro since 2017. Requirements Python 3.6+ 3.12+ uses os.splice natively; older versions fall back to ctypes Linux...

CVE-2026-80904 net/tls: Fail tls_sw_splice_read() after a failed async decrypt

In the Linux kernel, the following vulnerability has been resolved: net/tls: Fail tlsswspliceread after a failed async decrypt When an async decrypt fails, tlsdecryptdone records the error in ctx-asyncwait.err and calls tlserrabort, which stores it in skerr. tlsswrecvmsg and tlsswreadsock each re...

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...
