CVE-2026-43378 smb: server: fix use-after-free in smb2_open()
In the Linux kernel, the following vulnerability has been resolved: smb: server: fix use-after-free in smb2open The opinfo pointer obtained via rcudereferencefp-fopinfo is dereferenced after rcureadunlock, creating a use-after-free window...
CVE-2026-43378
CVE-2026-43378 affects the Linux kernel SMB server (smb2_open). A use-after-free arises because the opinfo pointer obtained via rcu_dereference(fp->f_opinfo) is dereferenced after rcu_read_unlock(), creating a use-after-free window. Multiple sources (SUSE, Red Hat, Debian OSV, Ubuntu, Debian t...

CVE-2026-43362
CVE-2026-43362 affects the Linux kernel SMB client by an in-place encryption flaw in SMB2_write(), where the write payload could be replaced with ciphertext during retries on unstable connections. The root cause is that smb3_init_transform_rq() shares rq_iov, causing crypt_message() to in-place-e...
CVE-2026-43362 smb: client: fix in-place encryption corruption in SMB2_write()
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix in-place encryption corruption in SMB2write SMB2write places write payload in iov1..n as part of rqiov. smb3inittransformrq pointer-shares rqiov, so cryptmessage encrypts iov1 in-place, replacing the original...
Linux kernel 安全漏洞
The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the pointer opinfo obtained through rcudereference in smb2open being rereferenced after rcureadunlock,...
