PT-2026-90284

In the Linux kernel, the following vulnerability has been resolved: kho: fix size calculation in kho preserved memory reserve kho preserved memory reserve calculates the size of a preservation by doing 1 order + PAGE SHIFT. Since the '1' is a 32-bit integer, it can only be shifted by 31. That is,...

CVE-2026-79590

A NULL pointer dereference vulnerability exists in the Prism parser component of mruby 4.0.0. An attacker can provide a specially crafted Ruby source file that triggers the parser to pass a NULL pointer to nonnull string handling functions, resulting in undefined behavior and application crash...

In the Linux kernel, the following vulnerability has been resolved: fuse: publish io-uring queues with release semantics fuseuringcreatequeue initializes a fuseringqueue and then publishes the pointer into ring-queuesqid with WRITEONCE under the fch-lock. There are several readers that may...

CVE-2026-80686

In the Linux kernel, the following vulnerability has been resolved: mm: migratedevice: fix ptepfn/ptedirty called on non-present PTE ptepfn and ptedirty have undefined behaviour when called on a non-present PTE. In migratevmacollectpmd, these functions may be invoked on non-present entries e.g.,...

EUVD-2026-67486

In the Linux kernel, the following vulnerability has been resolved: net: enetc: fix potential divide-by-zero when numvsi is zero For i.MX94 series, all the standalone ENETCs do not support SR-IOV, so pf-caps.numvsi is zero. This leads to a divide-by-zero in enetc4defaultringsallocation when...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: net: stmmac: fixed an issue with left shift overflow in DMA queues When the queue number is greater than 4, left shift overflows due to the 32-bit integer variable used in calculations. The mask calculation for MTLRXQDMAMAP1 i...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick within MagickCore/quantum.h. An attacker who submits a crafted file processed by ImageMagick could induce undefined behavior, resulting in values that fall outside the range of types float and unsigned char. This likely leads to a disruption in the application...

Astra Linux – Vulnerability in Thunderbird, Firefox

An invalid downcast from nsTextNode to SVGElement could result in undefined behavior. This vulnerability affects Firefox 110, Thunderbird 102.8, and Firefox ESR 102.8...

Astra Linux – Vulnerability in imagemagick

In the CropImage and CropImageToTiles routines of MagickCore/transform.c, rounding calculations performed on unconstrained pixel offsets were causing undefined behavior, including integer overflow and out-of-range values, as reported by UndefinedBehaviorSanitizer. Such issues could negatively...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick in the coders/txt.c file. An attacker who submits a crafted file processed by ImageMagick could trigger undefined behavior, resulting in values that are outside the range of the type unsigned long long. This likely leads to a disruption in the application’s...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bnxtre: Avoid undefined behavior in bnxtqpliballocinithwq. Undefined behavior occurs when bnxtqpliballocinithwq is called with hwqattr-auxdepth != 0 and hwqattr-auxstride == 0. In that case, rounduppowoftwohwqattr-auxstride is...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick in versions prior to 7.0.11 and prior to 6.9.12. In these versions, a division by zero in the WaveImage function of MagickCore/visual-effects.c could lead to undefined behavior when a malicious image file was submitted to an application that used ImageMagick...

Astra Linux – Vulnerability in Firefox and Thunderbird

The ShutdownObserver function was susceptible to potentially undefined behavior due to its reliance on a dynamic type that lacked a virtual destructor. This vulnerability affects Firefox ESR 115.6, Thunderbird 115.6, and Firefox 121...
