commit 24334f3cf8a294f253071b5bf22d754dbb6d0f2d
categpry: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICWGG2
CVE: CVE-2025-38691
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?24…
--------------------------------
The error occurs on the third attempt to encode extents. When function
ext_tree_prepare_commit() reallocates a larger buffer to retry encoding
extents, the "layoutupdate_pages" page array is initialized only after the
retry loop. But ext_tree_free_commitdata() is called on every iteration
and tries to put pages in the array, thus dereferencing uninitialized
pointers.
An additional problem is that there is no limit on the maximum possible
buffer_size. When there are too many extents, the client may create a
layoutcommit that is larger than the maximum possible RPC size accepted
by the server.
During testing, we observed two typical scenarios. First, one memory page
for extents is enough when we work with small files, append data to the
end of the file, or preallocate extents before writing. But when we fill
a new large file without preallocating, the number of extents can be huge,
and counting the number of written extents in ext_tree_encode_commit()
does not help much. Since this number increases even more between
unlocking and locking of ext_tree, the reallocated buffer may not be
large enough again and again.

[PATCH openEuler-1.0-LTS] scsi: libiscsi: Initialize iscsi_conn->dd_data only if memory is allocated
by Zheng Qixing 15 Sep '25
by Zheng Qixing 15 Sep '25
15 Sep '25
From: Showrya M N <showrya(a)chelsio.com>
mainline inclusion
from mainline-v6.17-rc1
commit 3ea3a256ed81f95ab0f3281a0e234b01a9cae605
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICWGGE
CVE: CVE-2025-38700
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
------------------
In case of an ib_fast_reg_mr allocation failure during iSER setup, the
machine hits a panic because iscsi_conn->dd_data is initialized
unconditionally, even when no memory is allocated (dd_size == 0). This
leads invalid pointer dereference during connection teardown.
Fix by setting iscsi_conn->dd_data only if memory is actually allocated.
Panic trace:
------------
iser: iser_create_fastreg_desc: Failed to allocate ib_fast_reg_mr err=-12
iser: iser_alloc_rx_descriptors: failed allocating rx descriptors / data buffers
BUG: unable to handle page fault for address: fffffffffffffff8
