UBUNTU-CVE-2026-74316

In the Linux kernel, the following vulnerability has been resolved: NFSD: Handle layout stid in nfsd4droprevokedstid nfsd4droprevokedstid has no SCTYPELAYOUT case, so when a client sends FREESTATEID for an admin-revoked layout stid, the default branch releases cllock and returns without unhashing...

CVE-2026-74358

In the Linux kernel, the following vulnerability has been resolved: ext4: fix fast commit wait/wake bit mapping on 64-bit On 64-bit, ext4 dynamic inode states live in the upper half of iflags, and ext4testinodestate applies the corresponding +32 offset. The fast-commit wait and wake paths...

UBUNTU-CVE-2026-74367

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix inconsistent arvif state in vdevcreate error paths ath12kmacvdevcreate has three error path issues that leave arvif in an inconsistent state: 1. When ath12kwmivdevcreate fails, the function returns directly...

CVE-2026-72256

In the Linux kernel, the following vulnerability has been resolved: netfilter: xtcluster: reject template conntracks in hash match xtclustermt treats any non-NULL nfctget result as a fully initialized conntrack and passes it to xtclusterhash. This causes a state confusion bug when the raw table C...

CVE-2026-72141

In the Linux kernel, the following vulnerability has been resolved: i2c: imx: fix locked bus on SMBus block-read of 0 IRQ SMBus 3.1 6.5.7 allows a Block Read byte count of 0, but the interrupt-driven block-read state machine rejects it as -EPROTO. Worse, it returns without a NACK+STOP: the next...

CVE-2026-72124

In the Linux kernel, the following vulnerability has been resolved: can: isotp: serialize TX state transitions under so-rxlock The TX state machine so-tx.state is driven from three contexts: sendmsg claiming and progressing a transfer, the RX path consuming Flow Control/echo frames, and two...

CVE-2026-72021

In the Linux kernel, the following vulnerability has been resolved: ipvs: use parsed transport offset in SCTP state lookup setsctpstate reads the SCTP chunk header again in order to drive the IPVS SCTP state table. For IPv6 it computes the offset with sizeofstruct ipv6hdr, while the surrounding...
