2025-02-27 CVE-2025-21711 Integer Overflow or Wraparound vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: net/rose: prevent integer overflows in rose_setsockopt() In case of possible unpredictably large arguments passed to rose_setsockopt() and multiplied by extra values on top of that, integer overflows may occur. Do the safest minimum and fix these issues by checking the contents of 'opt' and returning -EINVAL if they are too large.

2025-02-27 CVE-2025-21716 Use of Uninitialized Resource vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: vxlan: Fix uninit-value in vxlan_vnifilter_dump() KMSAN reported an uninit-value access in vxlan_vnifilter_dump() [1]. If the length of the netlink message payload is less than sizeof(struct tunnel_msg), vxlan_vnifilter_dump() accesses bytes beyond the message.

2025-02-27 CVE-2025-21718 Use After Free vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: net: rose: fix timer races against user threads Rose timers only acquire the socket spinlock, without checking if the socket is owned by one user thread. Add a check and rearm the timers if needed.

2025-02-26 CVE-2022-49566 Memory Leak vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: crypto: qat - fix memory leak in RSA When an RSA key represented in form 2 (as defined in PKCS #1 V2.1) is used, some components of the private key persist even after the TFM is released. Replace the explicit calls to free the buffers in qat_rsa_exit_tfm() with a call to qat_rsa_clear_ctx() which frees all buffers referenced in the TFM context.

2025-02-26 CVE-2022-49568 NULL Pointer Dereference vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: KVM: Don't null dereference ops->destroy A KVM device cleanup happens in either of two callbacks: 1) destroy() which is called when the VM is being destroyed; 2) release() which is called when a device fd is closed. Most KVM devices use 1) but Book3s's interrupt controller KVM devices (XICS, XIVE, XIVE-native) use 2) as they need to close and reopen during the machine execution.
