| In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix readahead synchronisation issues by loading all folios upfront
There are some synchronisation issues that derive from the app thread
adding more folios to the rolling buffer whilst the collector thread is
looking at them or trying to clear them, such as determining the setting of
front_folio_order when the next folio hasn't been added yet,
The reason for the rolling buffer approach is that loading the buffer
upfront and then dropping all the refs just acquired is quite a slow
operation, and loading progressively allows some of the cost to be deferred
until after at least some of the I/O is started.
Instead, a better way is to load all the folios into the rolling buffer
upfront - and then drop the refs later, once the I/O is in progress. (Even
better would be for the refs not to be there at all.)
Fix this by changing the rolling buffer loader to load all the folios
selected by the VM for readahead upfront into the folio queue. The folio
queue is allocated a batch worth at a time as we don't know how many folios
are involved (the readahead_control struct, alas, has a page count, not a
folio count).
The folio refs acquired from readahead are then dropped in bulk once the
first subrequest is dispatched as it's quite a slow operation. The
collector waits for NETFS_RREQ_NEED_PUT_RA_REFS to be cleared so that it
doesn't unlock folios before the xarray has been scanned for them.
This simplifies the buffer handling later and isn't noticeably slower as
the xarray doesn't need to be modified and the folios are all already
pre-locked. |
| A security flaw has been discovered in a2aproject a2a-rs up to 0.4.4. The affected element is the function InMemoryTaskStore::update of the file a2a-server/src/task_store/inmemory.rs. The manipulation results in race condition. The attack may be performed from remote. The patch is identified as 7050c7d329238539424ee46440e23b91c4825bee. It is advisable to implement a patch to correct this issue. |

| In the Linux kernel, the following vulnerability has been resolved:
ntfs: take invalidate_lock in ntfs_setattr_size()
ntfs_setattr_size() updates i_size and resizes the on-disk attribute
without holding mapping->invalidate_lock. Page faults take the lock
shared, so a fault racing the resize can resolve a VCN against the
transient runlist state of ntfs_non_resident_attr_expand() and fail
with a spurious SIGBUS, and can interleave with the size-change
epilogue (truncate_pagecache(), i_size_write(),
pagecache_isize_extended()).
Take invalidate_lock exclusively around the whole resize after
inode_dio_wait(), matching the fallocate path and other filesystems
such as xfs, which wraps truncate in its mmaplock (= invalidate_lock). |
| Use after free in Windows Ancillary Function Driver for WinSock allows an authorized attacker to disclose information locally. |
| Race condition in the IPC component. This vulnerability was fixed in Firefox 159, Firefox ESR 153.6, Thunderbird 159, and Thunderbird 153.6. |
| filelock is a platform-independent file lock for Python. From 4.1.0 until 4.2.1, SoftFileLock versions from 4.1.0 can reuse a stale observation when an attacker pre-dates and removes its own marker, at least two lock-user processes are waiting, coarse or matching modification times preserve the observation, and an honest contender creates a fresh marker on the reused inode, causing that live marker to be removed as stale. This issue is fixed in version 4.2.1. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Win32K allows an authorized attacker to elevate privileges locally. |
| A security vulnerability has been detected in a2aproject a2a-java up to 1.2.0.Final. This impacts the function TaskManager.saveTaskEvent. The manipulation leads to race condition. The attack may be initiated remotely. Upgrading to version 1.3.0.Final will fix this issue. The identifier of the patch is 6b8e1e085c35e970ef0048901cd25850e4791ec2. The affected component should be upgraded. |

| Wheels 3.0.0 through 4.1.1 can disclose detailed exceptions when allowIPBasedDebugAccess=true (disabled by default). An allowed administrator request changes error/debug-display settings in shared application scope. If it overlaps with an unauthorized client's request that raises an error, that client can receive full exception details, including tag context or a serialized exception, and any sensitive data they contain. This race does not bypass the production gate protecting developer tools. This is fixed in 4.1.2. |
