From aec00aa04b1131e17e6744681b380779f89d77b3 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 12 Apr 2021 17:01:01 +0100 Subject: KEYS: trusted: Fix missing null return from kzalloc call The kzalloc call can return null with the GFP_KERNEL flag so add a null check and exit via a new error exit label. Use the same exit error label for another error path too. Addresses-Coverity: ("Dereference null return value") Fixes: 830027e2cb55 ("KEYS: trusted: Add generic trusted keys framework") Signed-off-by: Colin Ian King Reviewed-by: Sumit Garg Reviewed-by: Jarkko Sakkinen Signed-off-by: Jarkko Sakkinen --- security/keys/trusted-keys/trusted_core.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'security/keys') diff --git a/security/keys/trusted-keys/trusted_core.c b/security/keys/trusted-keys/trusted_core.c index ec3a066a4b42..90774793f0b1 100644 --- a/security/keys/trusted-keys/trusted_core.c +++ b/security/keys/trusted-keys/trusted_core.c @@ -116,11 +116,13 @@ static struct trusted_key_payload *trusted_payload_alloc(struct key *key) ret = key_payload_reserve(key, sizeof(*p)); if (ret < 0) - return p; + goto err; p = kzalloc(sizeof(*p), GFP_KERNEL); + if (!p) + goto err; p->migratable = migratable; - +err: return p; } -- cgit v1.2.3
