Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: filemap: Avoid truncating the 64-bit offset to 32 bits. On 32-bit kernels, the folioseekholedata function inadvertently truncated a 64-bit value to 32 bits, which could lead to an infinite loop when writing to an xfs filesystem...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: iomap: Avoid truncating the 64-bit offset to 32 bits. On 32-bit kernels, iomapwritedelallocscan inadvertently used a 32-bit position due to folionextindex returning a unsigned long value. This could lead to an infinite loop when...

CVE-2026-80839

CVE-2026-80839 affects the batman-adv module in the Linux kernel . The root cause is that batadv_tvlv_call_handler() sets the 16-bit network and transport header offsets from a received multicast TVLV without validating whether the TVLV end offset is representable. When it exceeds the field's ran...

CVE-2026-80839 batman-adv: reject unrepresentable multicast TVLV offsets

In the Linux kernel, the following vulnerability has been resolved: batman-adv: reject unrepresentable multicast TVLV offsets The network and transport header fields in struct skbuff are 16-bit offsets from skb-head, and U16MAX is reserved as the unset transport header value. batadvtvlvcallhandle...
