In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix the warning division or modulo by zero Checks the partition mode and returns an error for an invalid mode...
kernel: NFSv4: Fix memory leak in nfs4_set_security_label
A vulnerability was found in the nfs4setsecuritylabel in the Linux kernel, where the function fails to free the nfsfattr attribute before exiting, leaving said memory allocation present. As the nfs4setsecuritylabel is called repeatedly over time, this may lead to memory exhaustion...
kernel: filelock: Remove locks reliably when fcntl/close race is detected
In the Linux kernel, the following vulnerability has been resolved: filelock: Remove locks reliably when fcntl/close race is detected When fcntlsetlk races with close, it removes the created lock with dolockfilewait. However, LSMs can allow the first dolockfilewait that created the lock while...
kernel: net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink()
A vulnerability was found in the icebridgesetlink function in the Linux kernel. A missing check to verify whether the nlmsgfindattr function returns NULL or not could lead to a NULL pointer dereference, system instability, or crashes...
kernel: xprtrdma: fix pointer derefs in error cases of rpcrdma_ep_create
A flaw was found in the Linux kernel in which a system crash can occur if there are certain errors establishing RPC-over-RDMA connections...
kernel: scsi: qedf: Ensure the copied buf is NUL terminated
In the Linux kernel, the following vulnerability has been resolved: scsi: qedf: Ensure the copied buf is NUL terminated Currently, we allocate a count-sized kernel buffer and copy count from userspace to that buffer. Later, we use kstrtouint on this buffer but we don't ensure that the string is...
kernel: nvmem: Fix shift-out-of-bound (UBSAN) with byte size cells
In the Linux kernel, the following vulnerability has been resolved: nvmem: Fix shift-out-of-bound UBSAN with byte size cells If a cell has 'nbits' equal to a multiple of BITSPERBYTE the logic p &= GENMASKcell-nbits%BITSPERBYTE - 1, 0; will become undefined behavior because nbits modulo BITSPERBYT...
kernel: ipv6: prevent NULL dereference in ip6_output()
In the Linux kernel, the following vulnerability has been resolved: ipv6: prevent NULL dereference in ip6output According to syzbot, there is a chance that ip6dstidev returns NULL in ip6output. Most places in IPv6 stack deal with a NULL idev just fine, but not here. syzbot reported: general...

SUSE CVE-2024-46744
In the Linux kernel, the following vulnerability has been resolved: Squashfs: sanity check symbolic link size Syzkiller reports a "KMSAN: uninit-value in picklink" bug. This is caused by an uninitialised page, which is ultimately caused by a corrupted symbolic link size read from disk. The reason...

DEBIAN-CVE-2024-46748
In the Linux kernel, the following vulnerability has been resolved: cachefiles: Set the max subreq size for cache writes to MAXRWCOUNT Set the maximum size of a subrequest that writes to cachefiles to be MAXRWCOUNT so that we don't overrun the maximum write we can make to the backing filesystem...
SUSE CVE-2024-46688
In the Linux kernel, the following vulnerability has been resolved: erofs: fix out-of-bound access when zerofsgbufgrowsize partially fails If zerofsgbufgrowsize partially fails on a global buffer due to memory allocation failure or fault injection as reported by syzbot 1, new pages need to be fre...
DEBIAN-CVE-2024-46709
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fix prime with external buffers Make sure that for external buffers mapping goes through the dmabuf interface instead of trying to access pages directly. External buffers might not provide direct access to...
