CVE-2026-43503

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: propagate shared-frag marker through frag-transfer helpers Two frag-transfer helpers pskbcopyfclone and skbshift fail to propagate the SKBFLSHAREDFRAG bit in skbshinfo-flags when moving frags from source to...

CVE-2026-46300

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: preserve shared-frag marker during coalescing skbtrycoalesce can attach paged frags from @from to @to. If @from has SKBFLSHAREDFRAG set, the resulting @to skb can contain the same externally-owned or page-cache-backe...

CVE-2026-46300

CVE-2026-46300 ("Fragnesia") is a local privilege escalation in the Linux kernel's ESP/XFRM (IPsec ESP-in-TCP) subsystem. The root cause is that skb_try_coalesce() fails to propagate the SKBFL_SHARED_FRAG marker when transferring paged fragments, causing ESP to skip skb_cow_data() and decrypt in ...

CVE-2026-43503

The CVE-2026-43503 entry concerns Linux kernel net/skbuff handling: when frags are moved by frag-transfer helpers (notably __pskb_copy_fclone() and skb_shift()), the SKBFL_SHARED_FRAG flag was not propagated to the destination skb, causing destination pages to remain shared while skb_has_shared_f...

PT-2026-42878

Name of the Vulnerable Software and Affected Versions Linux Kernel versions 7.1-rc1 through 7.1-rc4 Description A local privilege escalation issue exists in the networking stack skbuff due to the improper propagation of the SKBFL SHARED FRAG flag during fragment transfers. Several functions and...

kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...

kernel: net: skbuff: propagate shared-frag marker through frag-transfer helpers

A flaw was found in the Linux kernel's networking skbuff component. When skbtrycoalesce attaches paged fragments, it can lose the SKBFLSHAREDFRAG marker. This can lead to the Encapsulating Security Payload ESP input decrypting data in place over page-cache backed fragments, potentially resulting ...

kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...

USN-8277-1 linux, linux-aws, linux-hwe-6.17, linux-oem-6.17, linux-oracle, linux-raspi, linux-realtime, linux-realtime-6.17 vulnerabilities

It was discovered that the Linux kernel algifaead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-31431 Several security issues were discovered in th...

kernel: crypto: algif_aead - Revert to operating out-of-place

A flaw was found in the Linux kernel's algifaead cryptographic algorithm interface. An incorrect in-place operation causes source and destination data mappings to differ during cryptographic processing. A low-privileged local attacker can exploit this flaw to corrupt the contents of sensitive...

rust-openssl: Potential out-of-bounds write in `CipherCtxRef::cipher_update_inplace` for AES-KW-PAD ciphers

CipherCtxRef::cipherupdateinplace incorrectly sized output buffers when used with AES key-wrap-with-padding ciphers EVPaes128,192,256wrappad. For a non-multiple-of-8 input, OpenSSL writes up to 7 bytes past the end of the caller's buffer or Vec, producing attacker-controllable heap corruption whe...
