CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: remove stale channels from all sessions on teardown
ksmbd_sessions_deregister() removes a connection's channels from other
sessions' channel lists only while conn->binding is still set:
if (conn->binding) {
hash_for_each_safe(sessions_table, ...)
ksmbd_chann_del(conn, sess);
}
conn->binding is a transient flag: it is cleared once a binding
SESSION_SETUP completes, and also by a subsequent non-binding
SESSION_SETUP on the same connection (a reauthentication on a bound
channel, or a new SessionId==0 setup). A connection that has bound a
channel into another session's ksmbd_chann_list and then clears
conn->binding leaves that channel behind when it disconnects: the
channel, whose chann->conn points at the now freed struct ksmbd_conn,
stays on the owner session's list.
When the owning connection later tears down, the second loop
dereferences the stale channel:
xa_for_each(&sess->ksmbd_chann_list, chann_id, chann)
if (chann->conn != conn)
ksmbd_conn_set_exiting(chann->conn); /* freed */
which is a use-after-free write into the freed ksmbd_conn (the same
stale channel is also walked by show_proc_session() through /proc). The
session is leaked as well, because its channel list never empties.
Remove the conn->binding gate so a connection always removes its
channels from every session on teardown. |
| In the Linux kernel, the following vulnerability has been resolved:
isofs: handle set_blocksize failures
isofs uses buffer_heads, which don't handle block size > PAGE_SIZE well.
Without this, mounting we will hit the
BUG_ON(offset >= folio_size(folio));
in folio_set_bh on the first __bread_gfp call. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/ops-common: use a page-aligned address in damon_ptep_mkold()
__damon_va_prepare_access_check() picks a random byte address within the
region and stores it in r->sampling_addr. damon_va_mkold() passes it into
a page table walk, which hands it to damon_ptep_mkold() as the address of
the page to sample:
damon_va_mkold(mm, r->sampling_addr)
damon_va_walk_page_range(mm, addr, addr + 1)
damon_mkold_pmd_entry()
damon_ptep_mkold(pte, vma, addr)
ptep_test_and_clear_young(vma, addr, pte)
mmu_notifier_clear_young(mm, addr, addr + PAGE_SIZE)
For arm64, before commit 6f0e1142173a ("arm64: mm: support batch clearing
of the young flag for large folios"), the contpte helper walked exactly
CONT_PTES entries from the aligned-down page table pointer and used @addr
only to pass down to each entry, so an unaligned value was harmless:
ptep = contpte_align_down(ptep);
addr = ALIGN_DOWN(addr, CONT_PTE_SIZE);
for (i = 0; i < CONT_PTES; i++, ptep++, addr += PAGE_SIZE)
Now the range to walk is derived from @addr instead: end = addr + nr *
PAGE_SIZE, rounded up to CONT_PTE_SIZE. For a sample in the last page of
a contpte block, the sub-page offset puts end just past the block
boundary, so the round-up lands a whole block further and the walk clears
PTE_AF in CONT_PTES entries beyond the sampled block. For the last block
in a page table page, those entries are past the end of that page, so the
walk writes into the page that follows.
Triggered by the full 7.1/7.2 kernel selftest suite on arm64 (EC2
c/m6g.4xlarge). The kernel sometimes crashes at or shortly after the
DAMON test.
What the overrun does depends on the page that happens to follow the page
table, so there is no single signature. If that page is read-only, the
write faults in the sampling path itself:
Unable to handle kernel write to read-only memory at virtual address ffff0003c5d2d000
FSC = 0x0f: level 3 permission fault
CM = 0, WnR = 1, TnD = 0, TagAccess = 0

kthread+0x128/0x138
ret_from_fork+0x10/0x20
Otherwise the page is writable, the PTE_AF clearing succeeds silently and
the damage only surfaces later, in whatever happened to own the page, so
the backtrace is unrelated to DAMON and differs between runs.
Pass a page-aligned address to the ptep_test_and_clear_young() call in
damon_ptep_mkold(), which is the only place DAMON can reach
contpte_test_and_clear_young_ptes() from. Nothing else sees the aligned
address, and r->sampling_addr itself is left as is, so the sampling and
region bookkeeping semantics are unchanged. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: hub: use shorter 120ms post resume hold for SS root hubs
Holding a USB3 hub PM runtime reference for 200ms at hub resume triggers
an AMD platform issue. Users running Android adb report crashes after
adb has been polling and waking up the USB subsystem once a second for
some time. Vendors are working on a solution. Disabling USB runtime PM
is one way to prevent this issue, but it is also proven that reducing the
hold time to 120ms in resume also mitigates it. See Link for more
details.
Reducing the hold time to 120ms for the USB3 roothub is in itself a valid
change and optimization, as the current 200ms is excessive: a root hub
has no upstream suspended hub whose wake propagation needs to be
accounted for, but still need some time for USB3 link training to
complete.
Keep the 200ms hold for external hubs that commit 8f5b7e2bec1c
("usb: hub: fix detection of high tier USB3 devices behind suspended
hubs") is intended for. |
| Wasmtime is a runtime for WebAssembly. Prior to 36.0.19, 48.0.7, and 49.0.4, the Cranelift compiler backend on aarch64 can compile a Wasm br_table instruction with more than approximately 256,000 targets so that it has an incorrect conditional branch target. The branch can then jump to arbitrary other code at a user-controlled offset, allowing a user-controlled Wasm module to escape the sandbox on aarch64 engines using the default Cranelift backend. This issue is fixed in versions 36.0.19, 48.0.7, and 49.0.4. |
| Wasmtime is a runtime for WebAssembly. From 46.0.0 until 48.0.7 and 49.0.4, lowering a host-created component-model stream or future into a guest can omit a required payload-type check after the value passes through guest code and returns through StreamAny, FutureAny, Val::Stream, Val::Future, or an equivalent typed reader. A malicious guest that controls exported function types or returned values can cause the host to pass the type-erased value to a guest expecting a different payload type, which panics the Wasmtime host. This issue is fixed in versions 48.0.7 and 49.0.4. |
| Wasmtime is a runtime for WebAssembly. Prior to 36.0.19 and 43.0.0, the Cranelift compiler backend bit-packs SSA value indices in a way that can silently overflow in release builds when compiling a sufficiently large or specially crafted Wasm function with many SSA values. The overflow can make Cranelift reference incorrect IR values, causing arbitrary miscompilation, type confusion, and other attacker-controlled effects that may escape the Wasm sandbox on any architecture using the default Cranelift backend. This issue is fixed in versions 36.0.19 and 43.0.0. |
| GraphQL Scalars is a library of custom GraphQL scalars for creating precise type-safe GraphQL schemas. From 1.24.1 until 2.0.1, GraphQLPhoneNumber in src/scalars/PhoneNumber.ts uses ambiguous nested digit quantifiers that backtrack exponentially when a PhoneNumber value contains a run of digits followed by a character that makes the match fail. GraphQL evaluates parseLiteral during document validation and parseValue during variable coercion before resolver authentication or authorization, so a small unauthenticated request can block the Node.js event loop and stall the server process. serialize is also affected when unvalidated stored values are returned through the scalar. This issue is fixed in version 2.0.1. |
