kernel: rxrpc: Fix RxGK token loading to check bounds

A flaw was found in the Linux kernel's rxrpc subsystem. An unprivileged local user could exploit an integer overflow vulnerability in the rxrpcpreparsexdryfsrxgk function. This flaw occurs when processing specially crafted key and ticket lengths, causing an incorrect memory allocation size...

kernel: net: sched: UAF via missing handler for TC_ACT_CONSUMED in tcf_qevent_handle

A flaw was found in the Linux kernel's traffic control TC classifier application programming interface API. The tcfqeventhandle function does not properly handle a consumed socket buffer skb when it is processed by the defragmentation engine. This can lead to a Use-After-Free UAF vulnerability,...

CVE-2026-74445

A flaw was found in the Linux kernel's drm/vmwgfx component. A local attacker can trigger a null pointer dereference by sending a specially crafted command to the vmwcmddxbindquery function. This can lead to a kernel crash, resulting in a Denial of Service DoS for the affected system...

CVE-2026-72069

A flaw was found in the Linux kernel. The rtspinunlock function, and similar real-time RT locking mechanisms, incorrectly release Read-Copy-Update RCU protection before fully unlocking, leading to a Use-After-Free UAF vulnerability. This issue could allow a local attacker to potentially cause a...

CVE-2026-74506

A flaw was found in the Linux kernel's AFS Andrew File System component. A race condition exists in the afsmakecall function during asynchronous call reception and destruction when sending a message. This can lead to a Use-After-Free UAF vulnerability, where memory is improperly accessed after it...

CVE-2026-74491

A flaw was found in the Linux kernel. A null pointer dereference vulnerability exists within the ofpcirangeparserone function. This occurs when ofmatchbus returns a null value for nodes with specific range properties, which is then improperly dereferenced. An attacker could potentially exploit th...

CVE-2026-74471

A flaw was found in the Linux kernel's tracing subsystem. The tracemoduleaddevents function does not properly check the return value of registerevent. If event registration fails, a pointer to an event can still be created and retained even after the associated module memory is freed. This can le...

CVE-2026-72458

A flaw was found in the Linux kernel's Apparmor security module. This vulnerability occurs in the unpackpdb function, where it does not correctly handle a null pointer if a preceding operation, unpackdfa, fails. This oversight can lead to a NULL pointer dereference, which typically results in a...

CVE-2026-72373

A flaw was found in the AFS Andrew File System component of the Linux kernel. A missing NULL pointer check in the afsbreaksomecallbacks function could allow a local attacker to trigger a kernel panic, leading to a denial of service. This occurs when the afslookupvolumercu function returns a NULL...

CVE-2026-72490

A flaw was found in the Linux kernel's rtl8723bs Wi-Fi driver. An incorrect null-pointer guard in the rtwaesdecrypt function could lead to the system misinterpreting memory addresses. This issue may result in a system crash, causing a Denial of Service DoS...

CVE-2026-72189

A flaw was found in the Linux kernel's NTFS file system. During the process of shutting down a file system, a specific internal condition can arise where the system attempts to update an attribute list while an associated inode is being evicted. This can lead to a self-deadlock within the kernel'...

CVE-2026-19999

A buffer overflow in Assimp's ParseBoneTrafoKeys3DGSMDL7 function allows a remote attacker to cause a denial of service or potentially access sensitive information by tricking a user into loading a maliciously crafted 3DGS MDL7 file. Mitigation To mitigate this issue, avoid processing untrusted...

CVE-2026-72309

A flaw was found in the Linux kernel's tracing/remotes component. This vulnerability occurs when a page allocation fails within the traceremoteallocbuffer function. Due to an unincremented CPU counter, a partially allocated buffer descriptor rbdesc is not properly freed, leading to a memory leak...

CVE-2026-72454

A flaw was found in the Linux kernel's MIPI I3C Host Controller Interface HCI driver. A race condition in the i3chciaddrtodev function allows concurrent device addition or removal operations to modify a device list while it is being traversed without proper locking. This can lead to a...

CVE-2026-72292

A flaw was found in the kernel. A local user could exploit a vulnerability in the KVMS390GETCMMABITS ioctl, specifically within the kvms390getcmmabits function. This function allocates memory without properly initializing all pages, leading to uninitialized memory regions. These uninitialized...

GHSA-M44R-7C5H-M6MJ Medplum: Improper Validation of Redirect URI in External Auth Callback allows Authorization Code Leakage

Summary The external identity provider callback at GET /auth/external accepts attacker-controlled redirect URIs that only need to start with a registered client redirect URI, rather than matching exactly. After a successful external IdP login, the server appends Medplum login and code values to...

⚡ Weekly Recap: VMware Exploits, Windows 0-Day, MCP Attacks, Browser Hijacks and More

The expensive attacks are not always the clever ones. This week had plenty of proof. Exposed services got hit, old bugs found fresh use, browser sessions became attack paths, and supply-chain problems kept spreading farther than the original compromise. A lot of it came down to access that was...

389-ds-base: 389-ds-base: pre-authentication stack buffer overflow in get_ruvelement_from_berval() via unbounded replica ID parsing

A stack buffer overflow flaw was found in 389 Directory Server 389-ds-base. The getruvelementfromberval function in repl5ruv.c copies digit characters from a network-supplied RUV berval into a fixed 16-byte stack buffer without bounds checking. A remote unauthenticated attacker can crash the LDAP...
