| A vulnerability has been identified in SICAM GridEdge (Classic) (All versions < V2.7.3). The affected application uses an improperly protected file to import SSH keys. This could allow attackers with access to the filesystem of the host on which SICAM GridEdge runs to inject a custom SSH key to that file. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: xilinx: don't make a sleepable memory allocation from an atomic context

Fix it by passing the GFP_ATOMIC gfp flag for the corresponding
memory allocation. |
| A flaw was found in libvirt. The virStoragePoolObjListSearch function does not return a locked pool as expected, resulting in a race condition and denial of service when attempting to lock the same object from another thread. This issue could allow clients connecting to the read-only socket to crash the libvirt daemon. |
| In the Linux kernel, the following vulnerability has been resolved:
igb: revert rtnl_lock() that causes deadlock
The commit 6faee3d4ee8b ("igb: Add lock to avoid data race") adds
rtnl_lock to eliminate a false data race shown below
(FREE from device detaching) | (USE from netdev core)
igb_remove | igb_ndo_get_vf_config
igb_disable_sriov | vf >= adapter->vfs_allocated_count?
kfree(adapter->vf_data) |
adapter->vfs_allocated_count = 0 |
| memcpy(... adapter->vf_data[vf]
The above race will never happen and the extra rtnl_lock causes deadlock

Since the igb_disable_sriov() will call pci_disable_sriov() before
releasing any resources, the netdev core will synchronize the cleanup to
avoid any races. This patch removes the useless rtnl_(un)lock to guarantee
correctness. |
| A flaw was found in the blkgs destruction path in block/blk-cgroup.c in the Linux kernel, leading to a cgroup blkio memory leakage problem. When a cgroup is being destroyed, cgroup_rstat_flush() is only called at css_release_work_fn(), which is called when the blkcg reference count reaches 0. This circular dependency will prevent blkcg and some blkgs from being freed after they are made offline. This issue may allow an attacker with a local access to cause system instability, such as an out of memory error. |
| A race condition vulnerability was found in the vmwgfx driver in the Linux kernel. The flaw exists within the handling of GEM objects. The issue results from improper locking when performing operations on an object. This flaw allows a local privileged user to disclose information in the context of the kernel. |
| A flaw was found in the QEMU NBD Server. This vulnerability allows a denial of service (DoS) attack via improper synchronization during socket closure when a client keeps a socket open as the server is taken offline. |
| A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot. |
| In the Linux kernel, the following vulnerability has been resolved:
9p: trans_fd/p9_conn_cancel: drop client lock earlier
syzbot reported a double-lock here and we no longer need this
lock after requests have been moved off to local list:
just drop the lock earlier. |
| A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system. |

As the comment states, io_req_post_cqe() should only be used by
multishot requests, i.e. REQ_F_APOLL_MULTISHOT, which bundled sends are
not. Add a flag signifying whether a request wants to post multiple
CQEs. Eventually REQ_F_APOLL_MULTISHOT should imply the new flag, but
that's left out for simplicity. |
| The attacker can use the raft server protocol in an unauthenticated way. The attacker can see the server's resources, including directories and files.
This issue affects Apache Zeppelin: from 0.10.1 up to 0.12.0.
Users are recommended to upgrade to version 0.12.0, which fixes the issue by removing the Cluster Interpreter. |
| SENEC Storage Box V1,V2 and V3 accidentially expose a management UI accessible with publicly known admin credentials. |
| Cortex-A77 cores (r0p0 and r1p0) are affected by erratum 1508412
where software, under certain circumstances, could deadlock a core
due to the execution of either a load to device or non-cacheable memory,
and either a store exclusive or register read of the Physical
Address Register (PAR_EL1) in close proximity.

| An information disclosure vulnerability exists in the CtEnumCa() functionality of SoftEther VPN 4.41-9782-beta and 5.01.9674. Specially crafted network packets can lead to a disclosure of sensitive information. An attacker can send packets to trigger this vulnerability. |
| A memory initialization issue was addressed. This issue is fixed in macOS Ventura 13.3, macOS Monterey 12.6.4. A remote attacker may be able to cause unexpected app termination or arbitrary code execution. |
| p2putil.c in iNet wireless daemon (IWD) through 2.15 allows attackers to cause a denial of service (daemon crash) or possibly have unspecified other impact because of initialization issues in situations where parsing of advertised service information fails. |
| In the Linux kernel, the following vulnerability has been resolved:
dma-buf/sw-sync: don't enable IRQ from sync_print_obj()
Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from
known context") by error replaced spin_unlock_irqrestore() with
spin_unlock_irq() for both sync_debugfs_show() and sync_print_obj() despite
sync_print_obj() is called from sync_debugfs_show(), lockdep complains
inconsistent lock state warning.
Use plain spin_{lock,unlock}() for sync_print_obj(), for
sync_debugfs_show() is already using spin_{lock,unlock}_irq(). |
| In the Linux kernel, the following vulnerability has been resolved:
serial: max3100: Lock port->lock when calling uart_handle_cts_change()
uart_handle_cts_change() has to be called with port lock taken,
Since we run it in a separate work, the lock may not be taken at
the time of running. Make sure that it's taken by explicitly doing
that. Without it we got a splat:

md: fix resync softlockup when bitmap size is less than array size
Is is reported that for dm-raid10, lvextend + lvchange --syncaction will
trigger following softlockup:
kernel:watchdog: BUG: soft lockup - CPU#3 stuck for 26s! [mdX_resync:6976]

sectors = raid10_sync_request(mddev, j, &skipped)
if (!md_bitmap_start_sync(..., &sync_blocks))
// md_bitmap_start_sync set sync_blocks to 0
return sync_blocks + sectors_skippe;
// sectors = 0;
j += sectors;
// j never change
Root cause is that commit 301867b1c168 ("md/raid10: check
slab-out-of-bounds in md_bitmap_get_counter") return early from
md_bitmap_get_counter(), without setting returned blocks.
Fix this problem by always set returned blocks from
md_bitmap_get_counter"(), as it used to be.
Noted that this patch just fix the softlockup problem in kernel, the
case that bitmap size doesn't match array size still need to be fixed. |
