| In the Linux kernel, the following vulnerability has been resolved:
phy: rockchip: inno-usb2: Fix a double free bug in rockchip_usb2phy_probe()
The for_each_available_child_of_node() calls of_node_put() to
release child_np in each success loop. After breaking from the
loop with the child_np has been released, the code will jump to
the put_child label and will call the of_node_put() again if the
devm_request_threaded_irq() fails. These cause a double free bug.
Fix by returning directly to avoid the duplicate of_node_put(). |

Matthew has analyzed the report and identified that in drain_page_zone()
we are in a section protected by spin_lock(&pcp->lock) and then get an
interrupt that attempts spin_trylock() on the same lock. The code is
designed to work this way without disabling IRQs and occasionally fail the
trylock with a fallback. However, the SMP=n spinlock implementation
assumes spin_trylock() will always succeed, and thus it's normally a
no-op. Here the enabled lock debugging catches the problem, but otherwise
it could cause a corruption of the pcp structure.
The problem has been introduced by commit 574907741599 ("mm/page_alloc:
leave IRQs enabled for per-cpu page allocations"). The pcp locking scheme
recognizes the need for disabling IRQs to prevent nesting spin_trylock()
sections on SMP=n, but the need to prevent the nesting in spin_lock() has
not been recognized. Fix it by introducing local wrappers that change the
spin_lock() to spin_lock_iqsave() with SMP=n and use them in all places
that do spin_lock(&pcp->lock).
[vbabka@suse.cz: add pcp_ prefix to the spin_lock_irqsave wrappers, per Steven] |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: lpc18xx-dmamux: fix device leak on route allocation
Make sure to drop the reference taken when looking up the DMA mux
platform device during route allocation.
Note that holding a reference to a device does not prevent its driver
data from going away so there is no point in keeping the reference. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: storage: sddr55: Reject out-of-bound new_pba
Discovered by Atuin - Automated Vulnerability Discovery Engine.
new_pba comes from the status packet returned after each write.
A bogus device could report values beyond the block count derived
from info->capacity, letting the driver walk off the end of
pba_to_lba[] and corrupt heap memory.
Reject PBAs that exceed the computed block count and fail the
transfer so we avoid touching out-of-range mapping entries. |
| In the Linux kernel, the following vulnerability has been resolved:
net: sched: act_ife: initialize struct tc_ife to fix KMSAN kernel-infoleak
Fix a KMSAN kernel-infoleak detected by the syzbot .
[net?] KMSAN: kernel-infoleak in __skb_datagram_iter
In tcf_ife_dump(), the variable 'opt' was partially initialized using a
designatied initializer. While the padding bytes are reamined
uninitialized. nla_put() copies the entire structure into a
netlink message, these uninitialized bytes leaked to userspace.
Initialize the structure with memset before assigning its fields
to ensure all members and padding are cleared prior to beign copied.
This change silences the KMSAN report and prevents potential information
leaks from the kernel memory.
This fix has been tested and validated by syzbot. This patch closes the
bug reported at the following syzkaller link and ensures no infoleak. |
| In the Linux kernel, the following vulnerability has been resolved:
be2net: pass wrb_params in case of OS2BMC
be_insert_vlan_in_pkt() is called with the wrb_params argument being NULL
at be_send_pkt_to_bmc() call site. This may lead to dereferencing a NULL
pointer when processing a workaround for specific packet, as commit
bc0c3405abbb ("be2net: fix a Tx stall bug caused by a specific ipv6
packet") states.
The correct way would be to pass the wrb_params from be_xmit(). |

Input: cros_ec_keyb - fix an invalid memory access

`buttons_switches_only`) in cros_ec_keyb_probe(), `ckdev->idev` remains
NULL. An invalid memory access is observed in cros_ec_keyb_process()

It's still unknown about why the kernel receives such malformed event,

the driver doesn't intend to initialize them. |

Fix the field masks to match the hardware layout documented in

pinctrl: mcp23s08: Disable all pin interrupts during probe
A chip being probed may have the interrupt-on-change feature enabled on
some of its pins, for example after a reboot. This can cause the chip to
generate interrupts for pins that don't have a registered nested handler,
which leads to a kernel crash such as below:

This issue has always been present, but has been latent until commit
"f9f4fda15e72" ("pinctrl: mcp23s08: init reg_defaults from HW at probe and
switch cache type"), which correctly removed reg_defaults from the regmap
and as a side effect changed the behavior of the interrupt handler so that
the real value of the MCP_GPINTEN register is now being read from the chip
instead of using a bogus 0 default value; a non-zero value for this
register can trigger the invocation of a nested handler which may not exist
(yet).
Fix this issue by disabling all pin interrupts during initialization. |
| In the Linux kernel, the following vulnerability has been resolved:
ipvs: fix NULL deref in ip_vs_add_service error path
When ip_vs_bind_scheduler() succeeds in ip_vs_add_service(), the local
variable sched is set to NULL. If ip_vs_start_estimator() subsequently
fails, the out_err cleanup calls ip_vs_unbind_scheduler(svc, sched)
with sched == NULL. ip_vs_unbind_scheduler() passes the cur_sched NULL
check (because svc->scheduler was set by the successful bind) but then
dereferences the NULL sched parameter at sched->done_service, causing a
kernel panic at offset 0x30 from NULL.
Oops: general protection fault, [..] [#1] PREEMPT SMP KASAN NOPTI
KASAN: null-ptr-deref in range [0x0000000000000030-0x0000000000000037]

nf_setsockopt (net/netfilter/nf_sockopt.c:102)
[..]
Fix by simply not clearing the local sched variable after a successful
bind. ip_vs_unbind_scheduler() already detects whether a scheduler is
installed via svc->scheduler, and keeping sched non-NULL ensures the
error path passes the correct pointer to both ip_vs_unbind_scheduler()
and ip_vs_scheduler_put().
While the bug is older, the problem popups in more recent kernels (6.2),
when the new error path is taken after the ip_vs_start_estimator() call. |
