Astra Linux – vulnerability in linux-6.1, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: ksmbd: use aeadrequestfree to match aeadrequestalloc Use aeadrequestfree instead of kfree to properly free memory allocated by aeadrequestalloc. This ensures that sensitive crypto data is zeroed before being freed...

SUSE CVE-2026-64598

In the Linux kernel, the following vulnerability has been resolved: smb/client: Fix error code in smb2aeadreqalloc The "numsgs" variable is a u32 so "ERRPTRnumsgs" doesn't work. We would have to do something similar to the previous line where it's cast to int and then long. However, it's simpler ...

CVE-2026-64598

CVE-2026-64598 affects the Linux kernel SMB client in smb2_aead_req_alloc(). The bug arises because *num_sgs is a u32 and using ERR_PTR(*num_sgs) is incorrect; the fix stores the return in an int ret variable (instead of casting similarly to a prior line) to avoid dereferencing an invalid error p...

AZL-68846 CVE-2025-40052 affecting package kernel for versions less than 6.6.112.1-2

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix crypto buffers in non-linear memory The crypto API, through the scatterlist API, expects input buffers to be in linear memory. We handle this with the cifssgsetbuf helper that converts vmalloc'd memory to their...

CVE-2025-40052

CVE-2025-40052 (Linux kernel, SMB/CIFS crypto path) fixes a bug where aead_request context could end up in vmalloc memory, causing sg_set_buf() to crash when virt_addr_valid(buf) fails under heavy parallel I/O. Root cause: creq allocation used kvzalloc(), potentially placing __ctx in vmalloc area...

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix use-after-free in cryptmessage when using async crypto The CVE-2024-50047 fix removed asynchronous crypto handling from cryptmessage, assuming all crypto operations are synchronous. However, when hardware crypto...
