CVE-2026-43220 iommu/amd: serialize sequence allocation under concurrent TLB invalidations

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: serialize sequence allocation under concurrent TLB invalidations With concurrent TLB invalidations, completion wait randomly gets timed out because cmdsemval was incremented outside the IOMMU spinlock, allowing...

CVE-2026-43220

The CVE-2026-43220 entry concerns the Linux kernel iommu/amd component. The issue arises under concurrent TLB invalidations when CMD_COMPL_WAIT sequencing can be broken because cmd_sem_val was incremented outside the IOMMU spinlock, causing out-of-sequence command queuing and a disrupted completi...

CVE-2026-43182 media: ccs: Avoid possible division by zero

In the Linux kernel, the following vulnerability has been resolved: media: ccs: Avoid possible division by zero Calculating maximum M for scaler configuration involves dividing by MINXOUTPUTSIZE limit register's value. Albeit the value is presumably non-zero, the driver was missing the check it i...

CVE-2026-43182

Concrete details are available: CVE-2026-43182 affects the Linux kernel’s media: ccs component. The root cause is a missing check for a non-zero MIN_X_OUTPUT_SIZE limit register value when computing the maximum M for scaler configuration, risking a division-by-zero. Exploitation status is not pro...

In the Linux kernel, the following vulnerability has been resolved: powerpc/smp: Add check for kcalloc failure in parsethreadgroups As kcalloc may fail, check its return value to avoid a NULL pointer dereference when passing it to ofpropertyreadu32array...

CVE-2026-43141 ntb: ntb_hw_switchtec: Fix shift-out-of-bounds for 0 mw lut

In the Linux kernel, the following vulnerability has been resolved: ntb: ntbhwswitchtec: Fix shift-out-of-bounds for 0 mw lut Number of MW LUTs depends on NTB configuration and can be set to zero, in such scenario rounddownpowoftwo will cause undefined behaviour and should not be performed. This...

CVE-2026-43141

Summary : CVE-2026-43141 affects the Linux kernel ntb_hw_switchtec code, where the number of MW LUTs can be configured to zero. In that scenario, a call to rounddown_pow_of_two could trigger undefined behavior. The patch ensures rounddown_pow_of_two is only applied to a valid value. Impact : Unde...
