CVE-2026-53217

In CVE-2026-53217, the Linux kernel fix targets mvpp2 RX data synchronization. The issue arises when mvpp2 programs the RX queue offset and hardware writes data at dma_addr + MVPP2_SKB_HEADROOM, while the CPU sync starting at dma_addr only covers rx_bytes + MVPP2_MH_SIZE. On non-coherent DMA, thi...

CVE-2026-49271

libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.1, the uncompressed HEIF decoder validates explicit icef compressed-unit offsets using unitoffset + unitsize. Because the addition can wrap, a crafted HEIF file can pass the range check and then construct a vector...

In the Linux kernel, the following vulnerability has been resolved: loop: Overflow check during loop configuration The user space can configure a loop using an ioctl call. In this process, a configuration of type loopconfig is passed see the loioctl case on line 1550 of drivers/block/loop.c. This...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: vduse: It is now checked that the offset is within the bounds during the getconfig function. This check only examines “len”, but does not examine “offset”. This could lead to an out-of-bounds read if “offset dev-configsize” is...
