| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: vgic-its: Drop the translation cache reference only for the erased entry
vgic_its_invalidate_cache() walks the per-ITS translation cache with
xa_for_each() and drops the cache's reference on each entry with
vgic_put_irq(). It puts the iterated pointer, though, rather than the
value returned by xa_erase().
The function is called from contexts that do not exclude one another: the
ITS command handlers hold its_lock, the GITS_CTLR write path holds
cmd_lock, and the path that clears EnableLPIs in a redistributor's
GICR_CTLR holds neither. Two or more of them can drain the same cache
concurrently, and if each one observes the same entry, erases it and then
puts it, the single reference the cache holds on that entry is dropped
more than once. The entry can then be freed while an ITE still maps it.
xa_erase() is atomic and returns the previous entry, so put only the entry
that this context actually removed. The cache reference is then dropped
exactly once per entry even when the invalidations run concurrently, and
the behavior is unchanged when only one context runs. |
| In the Linux kernel, the following vulnerability has been resolved:
lib/scatterlist: fix length calculations in extract_kvec_to_sg
Patch series "Fix bugs in extract_iter_to_sg()", v3.
Fix bugs in the kvec and user variants of extract_iter_to_sg. This series
is growing due to useful remarks made by sashiko.dev.
The main bugs are:
- The length for an sglist entry when extracting from
a kvec can exceed the number of bytes in the page. This
is obviously not intended.
- When extracting a user buffer the sglist is temporarily
used as a scratch buffer for extracted page pointers.
If the sglist already contains some elements this scratch
buffer could overlap with existing entries in the sglist.
The series adds test cases to the kunit_iov_iter test that demonstrate all
of these bugs. Additionally, there is a memory leak fix for the test
itself.
The bugs were orignally introduced into kernel v6.3 where the function
lived in fs/netfs/iterator.c. It was later moved to lib/scatterlist.c in
v6.5. Thus the actual fix is only marked for backports to v6.5+.
This patch (of 5):
When extracting from a kvec to a scatterlist, do not cross page
boundaries. The required length was already calculated but not used as
intended.
Adjust the copied length if the loop runs out of sglist entries without
extracting everything.
While there, return immediately from extract_iter_to_sg if there are no
sglist entries at all.
A subsequent commit will add kunit test cases that demonstrate that the
patch is necessary. |
| In the Linux kernel, the following vulnerability has been resolved:
of: unittest: fix use-after-free in of_unittest_changeset()
The variable 'parent' is assigned the value of 'nchangeset' earlier in the
function, meaning both point to the same struct device_node. The call to
of_node_put(nchangeset) can decrement the reference count to zero and
free the node if there are no other holders. After that, the code still
uses 'parent' to check for the presence of a property and to read a
string property, leading to a use-after-free.
Fix this by moving the of_node_put() call after the last access to
'parent', avoiding the UAF. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/zone_device: do not touch device folio after calling ->folio_free()
The contents of a device folio can immediately change after calling
->folio_free(), as the folio may be reallocated by a driver with a
different order. Instead of touching the folio again to extract the
pgmap, use the local stack variable when calling percpu_ref_put_many(). |

| Idira Endpoint Privilege Manager Agent versions prior to 26.5 exhibit improper access control within high-privileged agent components. A local, low-privileged attacker could exploit this by manipulating an internal communication mechanism or file operation. Under specific circumstances, this could potentially allow the attacker to bypass permission restrictions and execute unauthorized local actions with elevated privileges. CyberArk Security Bulletin: CA26-19 |
| Idira Endpoint Privilege Manager Agent versions prior to 26.5 exhibit improper access control within internal agent validation processes. A local attacker could potentially bypass built-in security controls or cryptographic validations. Under specific circumstances, this could allow the attacker to circumvent agent self-defense mechanisms and execute unauthorized operations. CyberArk Security Bulletin: CA26-19 |
