SUSE CVE-2025-47711

There's a flaw in the nbdkit server when handling responses from its plugins regarding the status of data blocks. If a client makes a specific request for a very large data range, and a plugin responds with an even larger single block, the nbdkit server can encounter a critical internal error,...

SUSE CVE-2025-47712

A flaw exists in the nbdkit "blocksize" filter that can be triggered by a specific type of client request. When a client requests block status information for a very large data range, exceeding a certain limit, it causes an internal error in the nbdkit, leading to a denial of service...

CVE-2025-29956

Buffer over-read in Windows SMB allows an authorized attacker to disclose information over a network...

kernel: s390/dcssblk: fix kernel crash with list_add corruption

A kernel crash vulnerability was found in the Linux kernel's s390 dcssblk driver. Missing daxremovehost calls in the device removal path, combined with broken error handling in the device add path, cause stale xarray entries and listadd corruption. When a previously used gendisk pointer is reused...

kernel: ext4: make sure the first directory block is not a hole

The syzbot constructs a directory that has no dirblock but is non-inline, i.e. the first directory block is a hole. And no errors are reported when creating files in this directory. Then, we get a directory block without '.' and '..' but with a valid dentry. This may cause some code that relies o...

kernel: block: fix integer overflow in BLKSECDISCARD

A flaw was found in the Linux kernel's block subsystem. A local attacker with sufficient privileges could exploit an integer overflow vulnerability in the BLKSECDISCARD ioctl. This could lead to a near infinite loop within the blkdevissuesecureerase function, resulting in a Denial of Service DoS...

kernel: blk-mq: setup queue ->tag_set before initializing hctx

In the Linux kernel, the following vulnerability has been resolved: blk-mq: setup queue -tagset before initializing hctx Commit 7b815817aa58 "blk-mq: add helper for checking if one CPU is mapped to specified hctx" needs to check queue mapping via tag set in hctx's cpuhp handler. However, q-tagset...

kernel: smb: client: fix possible double free in smb2_set_ea()

A doubly freeing memory vulnerability exists in the Linux kernel smb client. After the first successful memory allocation for 'ea', the second memory release for 'ea' will result in double free, leading to loss of availability of the system...

kernel: net/sched: sch_api: fix xa_insert() error path in tcf_block_get_ext()

A flaw was found in the Linux kernel's network scheduling subsystem. When configuring traffic control rules with identical ingress and egress block identifiers, an error-handling failure prevents network flow blocks from properly unbinding on failure. A local user with network administration...

kernel: pmdomain: imx93-blk-ctrl: correct remove path

A flaw was found in the Linux kernel's i.MX93 power domain driver. An improper loop condition in the device removal routine prevents the loop from terminating. A local attacker could exploit this flaw during device unbinding or removal to trigger a kernel panic, resulting in a Denial of Service D...

kernel: block, bfq: fix bfqq uaf in bfq_limit_depth()

In the Linux kernel, the following vulnerability has been resolved: block, bfq: fix bfqq uaf in bfqlimitdepth Set new allocated bfqq to bic or remove freed bfqq from bic are both protected by bfqd-lock, however bfqlimitdepth is deferencing bfqq from bic without the lock, this can lead to UAF if t...

kernel: brd: defer automatic disk creation until module initialization succeeds

In the Linux kernel, the following vulnerability has been resolved: brd: defer automatic disk creation until module initialization succeeds My colleague Wupeng found the following problems during fault injection: BUG: unable to handle page fault for address: fffffbfff809d073 PGD 6e648067 P4D...

kernel: dm array: fix releasing a faulty array block twice in dm_array_cursor_end

In the Linux kernel, the following vulnerability has been resolved: dm array: fix releasing a faulty array block twice in dmarraycursorend When dmbmreadlock fails due to locking or checksum errors, it releases the faulty block implicitly while leaving an invalid output pointer behind. The caller ...

kernel: block: fix potential invalid pointer dereference in blk_add_partition

A flaw was found in the Linux kernel's block device subsystem. An invalid pointer dereference could occur within the blkaddpartition function due to incorrect error handling. A local attacker could exploit this vulnerability to cause a system crash, leading to a denial of service...

kernel: block: fix deadlock between sd_remove & sd_release

In the Linux kernel, the following vulnerability has been resolved: block: fix deadlock between sdremove & sdrelease Our test report the following hung task: 2538.459400 INFO: task "kworker/0:0":7 blocked for more than 188 seconds. 2538.459427 Call trace: 2538.459430 switchto+0x174/0x338...

kernel: Linux kernel: Denial of Service in erofs due to memory leak

A flaw was found in the Linux kernel's erofs filesystem. A local user can trigger a memory leak by exploiting a condition in the zerofsregisterpcluster function where a pcluster's block address is zero, leading to an unreleased reference count. This vulnerability can result in resource exhaustion...

kernel: pmdomain: imx8mp-blk-ctrl: add missing loop break condition

In the Linux kernel, the following vulnerability has been resolved: pmdomain: imx8mp-blk-ctrl: add missing loop break condition Currently imx8mpblkctrlremove will continue the for loop until an out-of-bounds exception occurs. pstate: 60000005 nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=-- pc :...
