CVE-2026-74709
In the Linux kernel, the following vulnerability has been resolved: xsk: clear metadata pointer when no timestamp is requested User space can change metadata flags after request processing. Rereading them during completion can therefore make the kernel write a timestamp that was not requested whe...
CVE-2026-74707
In the Linux kernel, the following vulnerability has been resolved: xsk: validate metadata when processing requests The zero-copy path validates TX metadata while obtaining the descriptor context, then reads it again later when preparing the hardware request. User space can change the metadata...
CVE-2026-74694
In the Linux kernel, the following vulnerability has been resolved: net/ncsi: fix heap OOB read in NCSICMDSENDCMD payload length ncsisendcmdnl takes the number of bytes to copy from the attacker-controlled ncsipkthdr.length field of the in-band packet header, while the source buffer is the...
CVE-2026-74668
In the Linux kernel, the following vulnerability has been resolved: packet: use consistent hardheaderlen in TXRING send path tpacketsnd reads dev-hardheaderlen independently for skb allocation and header construction in tpacketfillskb. Concurrent netdevice reconfiguration can therefore make the...
CVE-2026-74607
In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Serialize accesses to the owner and mirror list with separate lock Interaction between KVMCAPVMMOVEENCCONTEXTFROM and KVMCAPVMCOPYENCCONTEXTFROM can cause two separate issues: - in sevmigratefrom, when the destination K...
CVE-2026-74610
In the Linux kernel, the following vulnerability has been resolved: tls: don't leave a full plaintext skmsg ring unpushed When the copy path in tlsswsendmsglocked adds the fragment that fills the plaintext skmsg ring, it does not set fullrecord, so the record is left full and unpushed. A later...
CVE-2026-74611
In the Linux kernel, the following vulnerability has been resolved: tls: rx: restore msgiter before TLS 1.3 optimistic retry tlsdecryptsg advances msg-msgiter when it maps user pages for the optimistic TLS 1.3 zero-copy path. If the decrypted record turns out not to be unpadded application data,...
CVE-2026-74589
In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix skredir use-after-free in send verdict skpsockmsgverdict takes a socket reference for psock-skredir. tcpbpfsendverdict copies that pointer while holding the source socket lock, but does not take a reference for...
CVE-2026-74709
CVE-2026-74709 affects the AF_XDP (xsk) subsystem in the Linux kernel. The root cause is that user space can modify metadata flags after a TX request has been processed; when the kernel rereads those flags during completion, it may write a timestamp into the metadata area that was never requested...

CVE-2026-74707
CVE-2026-74707 affects the Linux kernel AF_XDP zero-copy TX path. The root cause is a TOCTOU (time-of-check to time-of-use) race : TX metadata is validated when obtaining the descriptor context, but read again later when preparing the hardware request. User space can modify the metadata between t...

CVE-2026-74694
CVE-2026-74694 is a heap out-of-bounds read in the Linux kernel's net/ncsi subsystem. The function ncsi_send_cmd_nl() trusts the attacker-controlled ncsi_pkt_hdr.length field from the in-band packet header without cross-checking it against the actual readable size of the NCSI_ATTR_DATA netlink at...
