CVE-2025-21873
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: bsg: Fix crash when arpmb command fails
If the device doesn't support arpmb we'll crash due to copying user data in bsg_transport_sg_io_fn().
In the case where ufs_bsg_exec_advanced_rpmb_req() returns an error, do not set the job's reply_len.
Memory crash backtrace: 3,1290,531166405,-;ufshcd 0000:00:12.5: ARPMB OP failed: error code -22
