CVE-2026-68167

A flaw was found in the Linux kernel's btrfs filesystem. A local user could trigger a kernel panic by performing specific filesystem operations that involve data relocation. This occurs because the system attempts to compress and inline data for relocation inodes, which are not designed for such...

CVE-2026-68289

A flaw was found in the Linux kernel. An integer overflow vulnerability exists within the Transparent Inter-Process Communication TIPC subsystem, specifically in the tipcrecvmsg and tipcrecvstream functions. This issue occurs when a buffer length value exceeds the maximum integer size, leading to...

CVE-2026-68336

A flaw was found in the Linux kernel's bonding module. When a system is booted with IPv6 disabled, the bonding module incorrectly attempts to send IPv6 Network Service NS packets. This leads to a null pointer dereference, which is an attempt to access uninitialized memory. The consequence of this...

CVE-2026-68179

A flaw was found in the Linux kernel's Network Shared Memory NSM module. A local attacker can exploit an issue in the nsmdevioctl function where an incorrect mutex unlock operation is performed. This occurs when an initial data copy fails, leading to an attempt to unlock a mutex that was never...

CVE-2026-68411

A flaw was found in the Linux kernel's mac80211hwsim component. A malicious backend device could report an oversized receive length to the hwsimvirtiorxwork function. This could cause the system to write past the end of a buffer, leading to a kernel panic and a denial of service DoS for the guest...

DEBIAN-CVE-2026-68289

In the Linux kernel, the following vulnerability has been resolved: tipc: fix integer overflow in tipcrecvmsg and tipcrecvstream In tipcrecvmsg, the copy length is computed as: copy = mintint, dlen - offset, buflen; buflen is sizet but mintint, ... casts it to int. When buflen exceeds INTMAX e.g...

EUVD-2026-55601

In the Linux kernel, the following vulnerability has been resolved: xfrm: clear mode callbacks after failed mode setup xfrmstategctask can run long after a failed IPTFS state setup. In the reproduced case, xfrminitstate cached x-modecbs, IPTFS setup returned -ENOMEM before publishing modedata, an...

CVE-2026-68172

In CVE-2026-68172, the Linux kernel arm64 path huge_ptep_get could mis-handle an unaligned virtual address pointing into the middle of a contpmd/contpte hugetlb folio. The arm64 helper rewalks pgtables to classify the huge PTE as CONT_PMDS or CONT_PTES, and, if the address isn’t aligned, could re...

EUVD-2026-55558

In the Linux kernel, the following vulnerability has been resolved: arm64: make hugeptepget handled unaligned addresses hugeptepget can be handed a virtual address pointing to the middle of a contpmd/contpte mapped hugetlb folio examples of callers are pagemaphugetlbrange, pagemappedinvma. The...

CVE-2026-68167

In the Linux kernel, the following vulnerability has been resolved: btrfs: do not try compression for data reloc inodes BUG There is a syzbot report that the check inside getnewlocation triggered: BTRFS info device loop0: found 31 extents, stage: move data extents BTRFS info device loop0: leaf...

CVE-2026-68136

In the Linux kernel CVE-2026-68136, the vulnerability stems from net: gro where skb_gro_receive_list() lacked a flush validation present in skb_gro_receive(), allowing already-GRO’d packets with a frag_list to be re-aggregated into a new GRO session. This can corrupt the frag_list chain and lead ...

CVE-2026-68135

In the Linux kernel, the following vulnerability has been resolved: net: hip04: fix RX buffer leak on buildskb failure When buildskb fails in hip04rxpoll, the driver jumps to the refill path without releasing the current RX buffer and its DMA mapping. Installing a replacement buffer then overwrit...

CVE-2026-68118

In the Linux kernel, the following vulnerability has been resolved: tcp: challenge ACK for non-exact RST in SYN-RECEIVED The SYN-RECEIVED request-socket path in tcpcheckreq accepts an in-window RST without requiring SEG.SEQ to exactly match RCV.NXT. A non-exact RST therefore removes the request...
