kernel: net/iucv: fix use-after-free of a severed iucv_path

A flaw was found in the Linux kernel. This use-after-free vulnerability exists in the net/iucv component. When a peer severs a connection, message notifications that still reference the freed connection path remain in a queue. A subsequent attempt to process these stale notifications can lead to...

kernel: svcrdma: Reject Write/Reply chunks with segcount 0

A flaw was found in the Linux kernel's Remote Procedure Call over Remote Direct Memory Access RPC-over-RDMA server component svcrdma. A remote peer can exploit this issue by transmitting a malformed Write or Reply chunk with a segment count of zero. Because the kernel fails to validate that the...

kernel: net/sched: cls_route: fix fastmap use-after-free on filter

A flaw was found in the Linux kernel's net/sched: clsroute component. A race condition exists in the route4 classifier's fastmap cache, where a reader can re-cache a pointer to a filter that has already been freed by a writer. This can lead to a use-after-free condition, allowing subsequent packe...

kernel: NFSD: Prevent client use-after-free during blocked-lock reaping

A flaw was found in the Linux kernel's Network File System Daemon NFSD. A use-after-free vulnerability can occur during the blocked-lock reaping process. This happens when a client's lock owner, without a proper reference to keep the client alive, leads to the client being prematurely freed. This...

kernel: svcrdma: Validate Read chunk positions before reconstruction

A flaw was found in the svcrdma component of the Linux kernel. A remote attacker can exploit this vulnerability by supplying a crafted RPC/RDMA Read chunk position field that is not properly validated against the received inline body length. This can lead to an underflow, exposing adjacent slab...

kernel: ALSA: usx2y: bound the hwdep mmap fault offset

A flaw was found in the Advanced Linux Sound Architecture ALSA usx2y driver in the Linux kernel. A local attacker, by opening the hwdep node of an attached US-X2Y device, could exploit an unbounded memory mapping mmap fault offset. This allows read-write access to arbitrary kernel memory,...

Microsoft.OpenApi.YamlReader vulnerable to denial of service via YAML alias expansion...

GHSA-7PXR-59RR-HQJ2 Microsoft.OpenApi.YamlReader vulnerable to denial of service via YAML alias expansion

Impact A small YAML OpenAPI document containing nested anchors and aliases can cause uncontrolled resource consumption in Microsoft.OpenApi.YamlReader and Microsoft.OpenApi.Readers. The issue affects OpenAPI document parsing through the public YAML reader APIs and can cause the parsing process to...

ipa: FreeIPA: Unauthenticated DoS in `/ipa/i18n_messages` via Unbounded Request Body Read

A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the /ipa/i18nmessages endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial o...

CVE-2026-63626

Mongoose is an embedded web server and network library. Prior to 7.23, ppphandleipv6cp in src/l2ppp.c trusts the 16-bit IPv6CP len field without checking it against the received payload size. On a PPP or PPPoE link using MGENABLETCPIP and MGENABLEIPV6, an unauthenticated adjacent peer can complet...

CVE-2026-109527

A flaw was found in mcp. This vulnerability allows an unauthenticated remote attacker to cause a Denial of Service DoS by exhausting system memory. Affected HTTP endpoints buffer incoming request bodies in memory without enforcing a maximum size limit. By sending excessively large or streamed...

mariadb: mariadb: Arbitrary code execution via crafted FRM metadata

A flaw was found in MariaDB. An attacker able to place a crafted table format FRM metadata file into the database data directory can exploit insufficient validation of metadata boundaries and field counts when the server opens the file. This could lead to out-of-bounds memory operations,...
