EUVD-2026-86980

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix percpu map update indexing with sparse CPU IDs Per-CPU array, hash, and cgroup storage map updates without BPFFCPU or BPFFALLCPUS use a value buffer whose per-CPU slots are packed in possible-CPU order. The buffer is siz...

CVE-2026-98149

The Linux kernel contains a vulnerability in the BPF subsystem related to how per-CPU array, hash, and cgroup storage maps are updated. When these maps are updated without the BPF_F_CPU or BPF_F_ALL_CPUS flags, the system uses a value buffer where slots are packed in possible-CPU order . However,...

EUVD-2026-86657

In the Linux kernel, the following vulnerability has been resolved: iommu/riscv: Serialize command queue publishing Serialize command queue publishing so software producer state advances only after a command is written and the hardware tail is updated. Wait for hardware consumption outside the...

CVE-2026-98004

The Linux kernel addresses a vulnerability within the iommu/riscv component related to command queue publishing. The fix ensures that the software producer state only advances after a command is written and the hardware tail is updated. To prevent other CPUs from being blocked by a long poll when...

CVE-2026-97985

The Linux kernel contains a vulnerability in the af_unix component where blocking recv(MSG_PEEK) operations could hog CPU resources. The issue occurs because manage_oob() skips Out-Of-Band (OOB) socket buffers and returns NULL for the last MSG_PEEK , failing to update the @last marker in unix_str...

EUVD-2026-86639

In the Linux kernel, the following vulnerability has been resolved: afunix: Update last skb marker in manageoob. Fahad Alharbi reported that blocking recvMSGPEEK could hog CPU due to OOB skb. In the following cases, manageoob skips OOB skbs and returns NULL for the last recvMSGPEEK:...

CVE-2026-97530

The Linux kernel contains a vulnerability in the scsi: qla2xxx driver where the functions qla27xx_copy_multiple_pkt() and qla27xx_copy_fpin_pkt() incorrectly poll for a specific signature (0xDEADDEAD ) to determine if the next continuation IOCB has arrived. Because a continuation IOCB carries raw...

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix soft lockup polling continuation IOCB signature qla27xxcopymultiplepkt and qla27xxcopyfpinpkt poll rspq-ringptr-signature for RESPONSEPROCESSED 0xDEADDEAD to decide whether the next continuation IOCB has arrive...

CVE-2026-97526

A vulnerability in the Linux kernel (s390/pai) allows for a kernel panic when CPUs are hotplugged during a perf stat command execution, specifically using pai_crypto/CRYPTO_ALL/. The root cause is the missing allocation of per-CPU data structures for newly added CPUs; the existing dynamic allocat...

CVE-2026-97526

In the Linux kernel, the following vulnerability has been resolved: s390/pai: Support CPU hotplug for PMU PAI The command 'perf stat -e paicrypto/CRYPTOALL/ -- ' crashes the kernel when CPUs are hotplug added during that run. Root cause is the missing allocation of per-CPU data structures for tha...
