CVE-2026-10646

Zephyr's BSD-sockets getaddrinfo implementation subsys/net/lib/sockets/getaddrinfo.c passes a pointer to a stack-allocated state object struct getaddrinfostate aistate as the userdata of an asynchronous DNS resolver query. The socket layer waits on a semaphore with a timeout deliberately set...

CVE-2026-10646 Use-after-return in `zsock_getaddrinfo()` when a timed-out DNS query is retried without cancellation

Zephyr's BSD-sockets getaddrinfo implementation subsys/net/lib/sockets/getaddrinfo.c passes a pointer to a stack-allocated state object struct getaddrinfostate aistate as the userdata of an asynchronous DNS resolver query. The socket layer waits on a semaphore with a timeout deliberately set...

CVE-2026-52950

A flaw was found in the Linux kernel, specifically within the drm/xe/dma-buf component. This Use-After-Free UAF vulnerability occurs due to an issue in a retry loop, where a buffer object is prematurely freed on error. An attacker could potentially exploit this to cause memory corruption, leading...

SUSE CVE-2026-52950

In the Linux kernel, the following vulnerability has been resolved: drm/xe/dma-buf: fix UAF with retry loop Retry doesn't work here, since bo will be freed on error, leading to UAF. However, now that we do the alloc & init before the attach, we can now combine this as one unit and have the init d...

CVE-2026-53058

A flaw was found in the drm/bridge: cadence: cdns-mhdp8546-core component of the Linux kernel. This vulnerability allows for a NULL pointer dereference during error handling within the atomicenable function. If cdnsmhdplinkup or cdnsmhdpregread encounter errors, a subsequent attempt to access a...

UBUNTU-CVE-2026-53191

In the Linux kernel, the following vulnerability has been resolved: iouring/net: inherit IORINGCQEFBUFMORE across bundle recv retries When a bundle recv retries inside iorecvfinish, the merge logic OR the saved cflags from the previous iteration with the cflags returned by the new iteration: cfla...

K000161900: Spring Retry vulnerability CVE-2026-41710

Security Advisory Description An attacker can craft a large number of unique requests that trigger a failure, exhausting the capacity of the application-wide stateful retry cache. Once the cache is full, it permanently rejects any further updates, causing all later stateful retries and circuit...

BIT-LIBPYTHON-2026-9669 bz2.BZ2Decompressor reuse after error can cause a stack buffer overflow

bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to resume from an invalid internal state and perform out-of-bounds writes to a stack buffer...

CVE-2026-54904

concurrent-ruby is a modern concurrency tools for Ruby. Prior to 1.3.7, Concurrent::AtomicReferenceupdate can enter a permanent busy retry loop when the current value is Float::NAN. The issue is caused by the interaction between AtomicReferenceupdate, which retries until compareandsetoldvalue,...

CVE-2026-52962

In the Linux kernel, the following vulnerability has been resolved: ceph: fix a buffer leak in cephsetxattr The oldblob in cephsetxattr can store ci-ixattrs.preallocblob value during the retry. However, it is never called the cephbufferput for the oldblob object. This patch fixes the issue of the...

CVE-2026-53060 dm cache metadata: fix memory leak on metadata abort retry

In the Linux kernel, the following vulnerability has been resolved: dm cache metadata: fix memory leak on metadata abort retry When failing to acquire the rootlock in dmcachemetadataabort because the blockmanager is read-only, the temporary blockmanager created outside the rootlock is not properl...

CVE-2026-53058

CVE-2026-53058 affects the Linux kernel DRM Cadence CDNS-MHDP8546 core in atomic_enable paths. The fault occurs when errors in cdns_mhdp_link_up() or cdns_mhdp_reg_read() cause a NULL pointer in modeset_retry_fn() because the connector isn’t initialised. The fix adds a connector_ptr to the mhdp d...
