CVE-2026-80670
A flaw was found in the Linux kernel's perf tools. The machineresolve function, responsible for resolving machine addresses, does not properly validate CPU index values from untrusted perf.data samples. A local attacker could provide a specially crafted perf.data file with a large CPU index,...

CVE-2026-80670 perf tools: Use perf_env__get_cpu_topology() in machine__resolve()
In the Linux kernel, the following vulnerability has been resolved: perf tools: Use perfenvgetcputopology in machineresolve machineresolve accesses env-cpual-cpu.socketid after checking al-cpu = 0 and env-cpu != NULL, but without validating al-cpu against env-nrcpusavail. Since al-cpu comes from...
CVE-2026-80670
CVE-2026-80670 affects the Linux kernel perf tools subsystem. The function machine__resolve() accesses env->cpu[al->cpu].socket_id after validating al->cpu >= 0 and env->cpu != NULL, but fails to validate al->cpu against env->nr_cpus_avail. Because al->cpu originates from ...
PT-2026-82970
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An out-of-bounds heap read exists in the machine resolve function. The issue occurs because the function accesses env-cpual-cpu.socket id without validating the al-cpu variable against...

SUSE CVE-2026-63859
In the Linux kernel, the following vulnerability has been resolved: net: airoha: Add missing bits in airohaqdmacleanuptxqueue Similar to airohaqdmacleanuprxqueue, reset DMA TX descriptors in airohaqdmacleanuptxqueue routine. Moreover, reset TXDMAIDX to TXCPUIDX to notify the NIC the QDMA TX ring ...
Linux Distros Unpatched Vulnerability : CVE-2026-64036
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - cgroup/rstat: validate cpu before cssrstatcpu access cssrstatupdated is exposed as a BPF kfunc and accepts a caller-provided cpu argument. The function uses cpu...
CVE-2026-63859
CVE-2026-63859 pertains to the Linux kernel driver for the airoha QDMA path. The fix adds missing steps in the airoha_qdma_cleanup_tx_queue() routine: it now resets DMA TX descriptors and sets TX_DMA_IDX to TX_CPU_IDX to signal that the QDMA TX ring is empty, mirroring the existing airoha_qdma_cl...
CVE-2022-49889 ring-buffer: Check for NULL cpu_buffer in ring_buffer_wake_waiters()
In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Check for NULL cpubuffer in ringbufferwakewaiters On some machines the number of listed CPUs may be bigger than the actual CPUs that exist. The tracing subsystem allocates a percpu directory with access to the per CP...
