UBUNTU-CVE-2025-40056
In the Linux kernel, the following vulnerability has been resolved: vhost: vringh: Fix copytoiter return value check The return value of copytoiter can't be negative, check whether the copied length is equal to the requested length instead of checking for negative values...
UBUNTU-CVE-2025-40053
In the Linux kernel, the following vulnerability has been resolved: net: dlink: handle copythresh allocation failure The driver did not handle failure of netdevallocskbipalign. If the allocation failed, dereferencing skb-protocol could lead to a NULL pointer dereference. This patch tries to...

In the Linux kernel, the following vulnerability has been resolved: vhost: vringh: Modify the return value check The return value of copyfromiter and copytoiter can't be negative, check whether the copied lengths are equal...
UBUNTU-CVE-2025-40036
In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: fix possible map leak in fastrpcputargs copytouser failure would cause an early return without cleaning up the fdlist, which has been updated by the DSP. This could lead to map leak. Fix this by redirecting to a...

CVE-2025-40056 vhost: vringh: Fix copy_to_iter return value check
In the Linux kernel, the following vulnerability has been resolved: vhost: vringh: Fix copytoiter return value check The return value of copytoiter can't be negative, check whether the copied length is equal to the requested length instead of checking for negative values...
CVE-2025-40056
The CVE is about Linux kernel vhost vringh: fix copy_to_iter return value check. The bug occurred because the code treated negative return values incorrectly; the patch now checks that the copied length equals the requested length instead of testing for negativity. This mode C entry is supported ...

CVE-2025-40051
CVE-2025-40051 affects the Linux kernel vhost vringh code. The issue arises from how copy_from_iter and copy_to_iter return values are handled: the code did not properly handle negative return values and did not verify that the copied lengths are equal, enabling potential misbehavior. The connect...
CVE-2025-40051 vhost: vringh: Modify the return value check

CVE-2025-40046
CVE-2025-40046 is a Linux kernel vulnerability in the io_uring zcrx path. The issue arises from io_zcrx_recv_skb() double-counting desc->count when handling frag lists, causing a recv limit overrun (buffers total > requested). This could impact availability (high) with limited confidentiali...
EUVD-2025-36493
In the Linux kernel, the following vulnerability has been resolved: Input: uinput - zero-initialize uinputffuploadcompat to avoid info leak Struct ffeffectcompat is embedded twice inside uinputffuploadcompat, contains internal padding. In particular, there is a hole after struct ffreplay to satis...

CVE-2025-40036
CVE-2025-40036 in the Linux kernel is resolved by fixing a map-leak in the fastrpc path. The vulnerability occurred when copy_to_user() could fail and cause an early return, leaving the fdlist updated by the DSP uncleared, potentially leaking maps. The fix redirects on failure to a cleanup path t...
