CVE-2026-23067

CVE-2026-23067 centers on an integer signedness bug in the Linux kernel’s ARM IOMMU path (io-pgtable-arm). __arm_lpae_unmap() returned a size_t (unsigned) but could yield -ENOENT on error, turning into a large positive value on 64-bit systems and propagating through the call chain to __iommu_unma...

In the Linux kernel, the following vulnerability has been resolved: iommu/io-pgtable-arm: fix size t signedness bug in unmap path arm lpae unmap returns size t but was returning -ENOENT negative error code when encountering an unmapped PTE. Since size t is unsigned, -ENOENT typically -2 becomes a...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Zero the value of ARGPTRTOLONG,INT in cases of errors. For all non-tracing helpers that previously had ARGPTRTOLONG,INT as input arguments, the value is set to zero in cases of errors. This prevents a potential memory leak...

AZL-50703 CVE-2024-47728 affecting package kernel 5.15.200.1-1

In the Linux kernel, the following vulnerability has been resolved: bpf: Zero former ARGPTRTOLONG,INT args in case of error For all non-tracing helpers which formerly had ARGPTRTOLONG,INT as input arguments, zero the value for the case of an error as otherwise it could leak memory. For tracing, i...
