CVE-2026-74583 net/sched: cls_route: fix fastmap use-after-free on filter

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsroute: fix fastmap use-after-free on filter The route4 classifier maintains a 16-slot fastmap cache that stores raw struct route4filter pointers indexed by id, iif. The reader route4classify populates this cache via...

CVE-2026-74583

CVE-2026-74583 is a use-after-free race condition in the Linux kernel's cls_route classifier (route4 fastmap cache). The route4_set_fastmap() reader can write a filter pointer into the 16-slot fastmap cache after a concurrent writer (route4_delete/route4_change) has already cleared it via route4_...

In the Linux kernel, the following vulnerability has been resolved: vhost: reset the vring metadata cache on vring reconfiguration vq-metaiotlb caches the vhostiotlbmap that backs each vring metadata region, and iotlbaccessok returns early on a cache hit, taking the hit as proof that the region h...

CVE-2026-74580

This vulnerability affects the Linux kernel's vhost subsystem . The vring metadata cache (vq->meta_iotlb[]) is not reset when VHOST_SET_VRING_ADDR or VHOST_SET_VRING_NUM reconfigures a virtual queue, causing iotlb_access_ok() to return early on a stale cache hit and skip re-validation. With a ...

Use of a Broken or Risky Cryptographic Algorithm

Overview Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm due to the extractContextHash logic in SemanticCacheAdvisor.java. An attacker can receive cached responses from an unrelated system prompt by sending requests whose prompts collide under...

CVE-2026-74576

A flaw was found in the Linux kernel's memory management. This vulnerability allows for unbounded recursion in the slab free path, a process where the kernel manages and releases small blocks of memory. When certain kernel memory allocation caches kmalloc caches form a cycle during internal data...

BIT-DISCOURSE-2026-55674 Discourse: Cache poisoning/XSS via color scheme cookies

Discourse is an open-source discussion platform. Prior to 2026.1.6, 2026.5.2, 2026.6.1, and 2026.7.0, an unauthenticated attacker could send a single request with a crafted colorschemeid or darkschemeid cookie to inject arbitrary HTML into a Discourse page. Because the cookie value was rendered...

CVE-2026-74487

A flaw was found in the binfmtmisc component of the Linux kernel. When a binfmtmisc entry is registered with the MISCFMTOPENFILE flag, it opens an interpreter file and denies write access. Upon removal of this entry, the write access is not properly restored. This oversight can lead to a persiste...
