CVE-2026-53164

The CVE-2026-53164 entry concerns the Linux kernel IOMMU DMA SWIOTLB path. The vulnerability arises when iommu_dma_iova_link_swiotlb() maps an unaligned memory region and, if the middle portion is empty, calls iommu_map() with a 0 size, which the iommu_pt implementation treats as illegal, corrupt...

PT-2026-52260

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the iommu dma iova link swiotlb function when processing unaligned mappings divided into head, middle, and trailer parts. If the middle section is empty due to a lack ...

CVE-2026-53076

The CVE covers a Linux kernel BPF issue: an out-of-bounds read in pcpu_init_value when copying data between BPF_MAP_TYPE_CGROUP_STORAGE and a pcpu map with the same value_size that is not 8-byte aligned. The verifier reads the source size exactly, but the copy path sometimes rounds up to 8 bytes ...

In the Linux kernel, the following vulnerability has been resolved: flowdissector: Do not dissect PPPoE PFC frames. RFC 2516, Section 7 states that Protocol Field Compression PFC is NOT recommended for PPPoE. In practice, pppd does not support negotiating PFC for PPPoE sessions, and the flow...

CVE-2026-52905

A flaw was found in the Linux kernel's Data Access MONitor DAMON core. The damonstart function, when used via the DAMON sysfs interface, failed to properly validate the minregionsz parameter. This allowed non-power of two values, which could lead to unaligned DAMON region address ranges and...
