glibc: glibc: Information disclosure or denial of service via ungetwc function with specific wide character encodings
A flaw was found in glibc GNU C Library. When the ungetwc function is called on a file stream using wide characters with specific overlapping single-byte and multi-byte encodings, it may attempt to read data outside of its allocated buffer. This can lead to the unintentional disclosure of sensiti...

CVE-2026-53134
A vulnerability in the Linux kernel netfilter NFT_FIB code (CVE-2026-53134) could leak uninitialized kernel stack via the OIFNAME result register on certain lookup-fail paths. The issue stems from NFT_FIB_RESULT_OIFNAME writes only a single byte and leaves the remaining IFNAMSIZ span stale in nft...
CVE-2026-46559 ImageMagick: Heap Buffer Over-Write of a single byte in the JP2 encoder
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-23, an incorrect check in the JP2 will result in an heap buffer over-write of a single byte when specifying certain options. This issue has been patched in versions...

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-47 and 7.1.2-22, an off by one in the meta encoder could result in an out of bounds read of a single byte in the meta encoder. This issue has been patched in versions 6.9.13-47...
CVE-2026-47066
Loop with Unreachable Exit Condition 'Infinite Loop' vulnerability in benoitc hackney allows Excessive Allocation. The Alt-Svc response header parser in src/hackneyaltsvc.erl does not guarantee forward progress. When parsetoken/2 receives a non-token, non-whitespace, non-comma byte e.g. !, @, =, ...
CVE-2026-47066
CVE-2026-47066 describes an Infinite Loop in the Alt-Svc header parser of benoitc’s hackney. The vulnerable component is the Alt-Svc response header parser (src/hackney_altsvc.erl); when parse_token/2 receives certain inputs, it may return the input unchanged, and skip_comma/1 can fail to progres...
ImageMagick: Heap Buffer Over-Write in json and yaml encoder of a single byte due to incorrect fix

Astra Linux – Vulnerability in dnsmasq
A single-byte, non-arbitrary write/use-after-free flaw was discovered in dnsmasq. This flaw allows an attacker to send a crafted packet processed by dnsmasq, potentially causing a denial of service...
Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: spi: sun6i – reduced the DMA RX transfer width to a single byte. Through empirical testing, it has been determined that sometimes RX SPI transfers with DMA enabled may return corrupted data. This issue arises due to the loss of o...
