CVE-2026-64449

CVE-2026-64449 relates to the Linux kernel staging/vme_user code. The vulnerability arises because the SLAVE-path helpers buffer_to_user() and buffer_from_user() copy count bytes using an unsafe offset (*ppos) into a fixed-size kern_buf (128 KiB), without bounding *ppos + count against size_buf. ...

CVE-2026-64449 staging: vme_user: bound slave read/write to the kern_buf size

In the Linux kernel, the following vulnerability has been resolved: staging: vmeuser: bound slave read/write to the kernbuf size The SLAVE-path helpers buffertouser and bufferfromuser copy 'count' bytes into/out of the fixed-size kernbuf sizebuf == PCIBUFSIZE == 0x20000, 128 KiB using ppos as the...

CVE-2026-64392

The CVE-2026-64392 entry concerns the Linux kernel ksmbd delete-on-close path. The underlying issue was that delete-on-close could execute unlink and ADS xattr removal with ksmbd worker credentials rather than the credentials captured at file open, allowing potential permission checks bypass. The...

CVE-2026-64392 ksmbd: use opener credentials for delete-on-close

In the Linux kernel, the following vulnerability has been resolved: ksmbd: use opener credentials for delete-on-close Delete-on-close can be completed by deferred or durable handle teardown, where no request work is available. Both the base-file unlink and the ADS xattr removal consequently run...
